                                   ----------

      This Prospectus  relates to the public offering of 1,001,333 shares of our
Common Stock,  par value $.10 per share. Of the total 1,001,333 shares of Common
Stock being registered,  801,333 shares are being registered for the accounts of
the selling stockholders identified in Table A of the section of this Prospectus
entitled "Selling Stockholders".  The remaining 200,000 of such shares are being
registered for the account of Joseph C. Abeles,  who is one of our directors and
the owner of a $600,000 Senior Convertible Subordinated Debenture issued by us.

      This  offering  will not be  underwritten.  All  1,001,333  shares  may be
offered by certain of our  stockholders or by pledgees,  donees,  transferees or
other  successors-in-interest  who  receive  the  shares as a gift,  partnership
distribution or other non-sale related transfer.  Of the 1,001,333 shares of our
Common Stock being registered,  801,333 shares were originally issued in private
transactions  pursuant to the terms of Stock Purchase  Agreements by and between
us and each of the  stockholders  identified  in the section of this  Prospectus
entitled "Selling Stockholders". The Debenture, which will automatically convert
into  the  remaining  200,000  shares  of  Common  Stock  upon  approval  of the
conversion  at our Annual  Meeting of  Shareholders  scheduled  to take place in
December 2002, was issued in a private transaction pursuant to the terms of that
certain Debenture Purchase Agreement by and between us and Mr. Abeles.

      The  issuance of the  Debenture  and shares of our Common Stock was exempt
from  registration  pursuant to Section 4(2) of the  Securities  Act of 1933, as
amended,  and Regulation D, as promulgated  under the Securities Act of 1933. We
are  registering the shares of our Common Stock pursuant to the terms of certain

      The shares of Common Stock that we are  registering  may be offered by the
selling  stockholders  (including  those holding stock as a result of the future
conversion  of  the  Debenture)  from  time  to  time  in  transactions  in  the
over-the-counter market, in negotiated transactions, or in a combination of such
methods of sale.  The shares may be offered at fixed prices that may be changed,
at market prices prevailing at the time of sale, at prices related to prevailing
market prices or at negotiated prices. The selling stockholders (including those
holding stock as a result of the future  conversion of the Debenture) may effect
such transactions by selling the shares to or through  broker-dealers,  and such
broker-dealers may receive compensation in the form of discounts, concessions or
commissions  from the selling  stockholders  (including those holding stock as a
result of the future  conversion of the Debenture)  and/or the purchasers of the
shares  for whom  such  broker-dealers  act as  agents  or to whom  they sell as
principals,  or  both.  This  compensation  might  be  in  excess  of  customary
commissions.  For  further  information,  see  the  section  entitled  "Plan  of
Distribution" below.

      We will not receive any of the proceeds from the sale of the shares of our
Common Stock.  We have agreed to bear certain  expenses in  connection  with the
registration  of the shares of our Common  Stock  being  offered and sold by the
selling  stockholders  (including  those holding stock as a result of the future
conversion of the Debenture).  Our Common Stock is quoted on the Nasdaq National

Our Business

      We develop, manufacture and market a wide range of standard and customized
primary  and  rechargeable  lithium  batteries  for  use  in  a  wide  array  of
applications and markets, including military,  automotive telematics, safety and
medical,  and  computers  and  communications.  We believe that our  proprietary
technologies  allow us to offer batteries that are ultra-thin,  light weight and
that  generally  achieve  greater  operating  performance  than other  batteries
currently  available.  We sell  our  products


                                      -2-


directly to original equipment manufacturers in the United States and abroad and
have contractual arrangements with sales representatives who market our products
on a commission  basis in particular  areas.  We also distribute our products to
domestic  and  international   distributors  and  retailers  that  purchase  our
batteries for resale.  We have obtained ISO 9001  certification  for our lithium
batteries manufacturing operations in Newark, New York and Abingdon, England. As
of May 31, 2002, we had approximately 350 employees worldwide.

      We were formed in December 1990 as a Delaware corporation.  In March 1991,
we acquired certain technology and assets from Eastman Kodak Company relating to
its 9-volt  lithium  manganese  dioxide  primary  battery and in June 1994, as a
result of the formation of our United  Kingdom  subsidiary  and  acquisition  of
certain battery-related assets, acquired a presence in Europe. In December 1998,
we announced a joint  venture to produce our polymer  rechargeable  batteries in
Taiwan.

      Our  principal  executive  office is located at 2000  Technology  Parkway,
Newark, New York 14513. Our telephone number is (315) 332-7100.

                                  RISK FACTORS

      An  investment in shares of Common Stock  offered  hereby  involves a high
degree of risk.  The following  risk factors  should be considered  carefully in
addition to the other  information  in this  Prospectus  before  purchasing  the
Common Stock  offered by this  Prospectus.  The  following  factors  could cause
actual  results  to  differ   materially  from  the  matters  described  in  the
forward-looking  statements,  with material and adverse effects on our business,
operating results, financial condition and the value of our stock.

History of Operating Losses; Uncertainty of Future Profitability

      We began operating our company in March 1991. During each year since 1991,
we have had net operating  losses.  These losses have  resulted  mainly from the
cost of researching,  developing and  manufacturing our products and general and
administrative  costs associated with operating our company. We may not generate
an operating profit or achieve profitability in the future.

Uncertainty  of Our Ability to Generate  Positive  Cash Flows and  Continue as a
Going Concern

      We have  experienced  negative cash flow since our inception.  Our current
cash and  credit  situation  is  strained.  While we are  focusing  intently  on
increasing  revenues  and reducing  costs and  expenses,  these  efforts may not
generate cash. Our failure to successfully  attain positive cash flow could have
a material  adverse  effect on the our business,  financial  condition,  and the
results  of our  operations.  Such  material  adverse  effects  could  include a
violation of debt covenants, an inability to pay vendors in a timely fashion, or
could  impact  upon  our  ability  to  continue  as a going  concern.  If we are
unsuccessful  in generating  positive cash flows,  we may need to access capital
markets for additional debt or equity  funding,  and we may not be successful in
doing so.

Uncertainty of Our Ability to Borrow Money to Fund Our Operations

      In October 2001, we were informed by our primary lending  institution that
our  borrowing  availability  under our  credit  facility  had been  effectively
reduced to zero as a result of an  appraisal  of our fixed  assets.  In February
2002, our primary lending  institution amended the credit facility to reduce our
available  line of credit from  $20,000,000  to  $15,000,000,  mainly due to the
reduction in the  valuation of our fixed  assets,  which  limited our  borrowing
capacity under the term loan component,  as well as minimized the cost of unused
line fees. Additionally, the term loan and revolving line components of our


                                      -3-


line of credit were  revised and the minimum  net worth  covenant  was  reduced.
While  these  changes to the  credit  facility  improve  our  overall  financial
flexibility,  our  future  liquidity  depends  on our  ability  to  successfully
generate  positive cash flow from  operations and achieve  adequate  operational
savings.  We may not have sufficient  credit available to us to meet our working
capital and capital expenditure requirements.

Uncertainty of Current and Future Demand for Our Primary Battery Products

      Although we are currently producing various primary battery products, this
demand  may not  continue.  We are in the  process  of  developing  new  battery
configurations for use in the manufacture of original equipment and for military
applications.  Such  products  may not be accepted in the market.  Additionally,
while we have recently been awarded a contract to supply  several  models of our
non-rechargeable  batteries to the U.S.  Army's  Communications  and Electronics
Command,  our  products  may not pass  military  qualification  standards in the
future. Our inability to manufacture and sell new products could have a material
adverse  effect on our  business,  financial  condition  and the  results of our
operations.

Uncertainty of Market Acceptance of Advanced Rechargeable Batteries

      Although we have begun volume  production of our  rechargeable  batteries,
our advanced rechargeable batteries have not yet achieved wide acceptance in the
market. The market may not ever accept our advanced rechargeable batteries.  The
introduction  of new  products is subject to the  inherent  risks of  unforeseen
delays and the time  necessary  to achieve  market  success  for any  individual
product is uncertain.  If volume  production  and/or market  penetration  of our
advanced  rechargeable  batteries is delayed for any reason, our competitors may
introduce  emerging  technologies or improve existing  technologies  which could
have a material  adverse  effect on our  business,  financial  condition and the
results of our operations.

Need to Create New Jobs to Fulfill Conditions of Government Grants

      In November 2001, we received  approval for two grants from New York State
and a  federally  sponsored  small  cities  program in the  aggregate  amount of
$1,050,000. The grants will assist us in funding current capital expansion plans
that we expect  will  lead to job  creation.  However,  in  connection  with the
receipt of the grants,  we are  obligated to create a certain  level of new jobs
over the next five years. Our capital  expansion may not lead to the creation of
a sufficient  number of jobs to satisfy the  employment  quotas  required by the
government  grants.  If we do not  meet  these  employment  quotas,  we could be
required to pay back a portion of the amount of the grants.

Dependence on OEM Relationships  and Products for Sale of Advanced  Rechargeable
Batteries

      We will  continue to promote  market  demand for,  and  awareness  of, our
advanced  rechargeable  batteries.  We will  accomplish  this partly through the
development of relationships  with original  equipment  manufacturers,  or OEMs,
that  manufacture  products  requiring the  performance  characteristics  of our
advanced  rechargeable  batteries.  The success of any such relationship depends
upon the general  business  condition  of the OEM and our ability to produce our
advanced  rechargeable  batteries  at the quality and cost and within the period
required  by  such  OEMs.  Our  failure  to  develop  a  sufficient   number  of
relationships  with OEMs could have a material  adverse  effect on our business,
financial condition and results of operations.

      A  substantial  portion of our  business  will  depend upon the success of
products  sold by OEMs  that  use  our  batteries.  Therefore,  our  success  is
substantially  dependent  upon  the  acceptance  of the  OEMs'  products  in the
marketplace.  We are subject to many risks beyond our control that influence the
success


                                      -4-


or  failure  of  a  particular  product   manufactured  by  an  OEM,  including,
competition  faced by the OEM in its particular  industry;  market acceptance of
the OEM's product; the engineering, sales, marketing and management capabilities
of the OEM; technical  challenges  unrelated to our technology or products faced
by the OEM in developing its products; and, the financial and other resources of
the OEM.

Risks Relating to Growth and Expansion

      Rapid  growth  of our  advanced  rechargeable  battery  business  or other
segments of our business may significantly strain our management, operations and
technical  resources.  If we are successful in obtaining  rapid market growth of
our  advanced  rechargeable  batteries,  we will be  required  to deliver  large
volumes of quality  products to our  customers on a timely basis at a reasonable
cost to those  customers.  Our  business may not rapidly grow and our efforts to
expand our  manufacturing  and quality control  activities may be  unsuccessful.
Likewise, we may not be able to satisfy commercial scale production requirements
on a timely and  cost-effective  basis.  We will also be required to continue to
improve our  operations,  management  and financial  systems and  controls.  Our
failure  to manage our growth  effectively  could have an adverse  effect on our
business, financial condition and the results of our operations.

Competition; Technological Obsolescence

      The primary and rechargeable  battery industry is characterized by intense
competition,  with a large  number of  companies  offering or seeking to develop
technology  and products  similar to ours.  We are subject to  competition  from
manufacturers  of traditional  rechargeable  batteries,  such as nickel- cadmium
batteries,   from  manufacturers  of  rechargeable   batteries  of  more  recent
technologies,  such as nickel-metal hydride,  lithium-ion liquid electrolyte and
lithium-ion  solid-polymer  batteries,  as well as from companies engaged in the
development of batteries incorporating new technologies.

      Manufacturers of nickel-cadmium and nickel-metal hydride batteries include
Eveready,  Sanyo  Electric  Co.  Ltd.,  Sony Corp.,  Toshiba  Corp.,  Matsushita
Electric Industrial Co., Ltd. and Duracell International,  Inc. Manufacturers of
lithium-ion  liquid  electrolyte  batteries  currently include Saft-Soc des ACC,
Sony Corp.,  Toshiba Corp.,  Matsushita  Electric  Industrial  Co., Ltd.,  Sanyo
Electric Co. Ltd. and Duracell  International,  Inc. Valence  Technology,  Inc.,
Lithium Technology Corporation,  and Yuasa-Exide,  Inc. have developed prototype
solid-polymer  batteries  and are  constructing  commercial-scale  manufacturing
facilities.  We also  compete  with large and small  manufacturers  of alkaline,
carbon-zinc,  seawater,  high  rate  and  primary  batteries  as well  as  other
manufacturers of lithium batteries.

      We may not successfully  compete with these  manufacturers,  many of which
have substantially greater financial,  technical,  manufacturing,  distribution,
marketing,  sales and other resources. Many companies with substantially greater
resources than ours are developing a variety of battery technologies,  including
liquid electrolyte  lithium and solid electrolyte  lithium batteries,  which are
expected to compete with our technology.  Other companies  undertaking  research
and development  activities of  solid-polymer  batteries have already  developed
prototypes and are constructing commercial scale production facilities. If these
companies  successfully  market their batteries  before the  introduction of our
products,  there could be a material  adverse effect on our business,  financial
condition   and  results  of   operations.   The  market  for  our  products  is
characterized  by changing  technology and evolving  industry  standards,  often
resulting in product obsolescence or short product lifecycles.

      Although  we  believe  that our  batteries,  particularly  our  9-volt and
advanced rechargeable batteries,  are comprised of state-of-the-art  technology,
there can be no assurance  that  competitors  will not develop  technologies  or
products  that  would  render  our  technology  and  products  obsolete  or less
marketable.


                                      -5-


Dependence on Key Personnel

      Because  of the  specialized,  technical  nature of our  business,  we are
highly  dependent on certain members of our management,  marketing,  engineering
and technical staff. If we lose the services of these members, this could have a
material adverse effect on our business,  financial condition and the results of
our operations.  In addition to developing manufacturing capacity so that we can
produce high volumes of our advanced  rechargeable  batteries,  we must attract,
recruit and retain a sizeable workforce of technically competent employees.  Our
ability to pursue  effectively  our business  strategy  will depend upon,  among
other factors,  the successful  recruitment  and retention of additional  highly
skilled  and  experienced  managerial,   marketing,  engineering  and  technical
personnel. We may not be able to retain or recruit this type of personnel.

Safety Risks; Demands of Environmental and Other Regulatory Compliance

      Components of our  batteries  contain  certain  elements that are known to
pose safety risks. Our primary battery products incorporate lithium metal, which
when it reacts with water may cause fires if not handled  properly.  In addition
to a December  1996 fire at our  Abingdon,  England  facility,  a fire  occurred
August 1997 at our Newark, New York facility and fires occurred in July 1994 and
September  1995 at our Abingdon,  England  facility,  each of which  temporarily
interrupted  certain  manufacturing  operations  in a  specific  area  of  these
facilities.   Although  we  incorporate   safety  procedures  in  our  research,
development  and  manufacturing  processes that are designed to minimize  safety
risks, more accidents may occur.  Although we currently carry insurance policies
which cover loss of our plant and machinery,  leasehold improvements,  inventory
and business interruption, any accident, whether at our manufacturing facilities
or from the use of our products,  may result in significant production delays or
claims for damages  resulting from injuries.  These types of losses could have a
material adverse effect on our business,  financial condition and the results of
our operations.

      National,  state and local laws impose various  environmental  controls on
the  manufacture,  storage,  use and  disposal  of lithium  batteries  and/or of
certain  chemicals  used in the  manufacture of lithium  batteries.  Although we
believe  that  our  operations  are  in  substantial   compliance  with  current
environmental  regulations  and  that,  except  as  noted  below,  there  are no
environmental conditions that will require material expenditures for clean-up at
our present or former facilities or at facilities to which it has sent waste for
disposal,  there can be no assurance  that changes in such laws and  regulations
will not impose costly compliance  requirements on we or otherwise subject it to
future liabilities.  Moreover,  state and local governments may enact additional
restrictions relating to the disposal of lithium batteries used by our customers
which could have a material adverse effect on our business,  financial condition
and results of operations.  In addition,  the U.S.  Department of Transportation
and certain foreign regulatory  agencies that consider lithium to be a hazardous
material  regulate the  transportation of batteries which contain lithium metal.
We  currently  ship  our  lithium   batteries  in  accordance  with  regulations
established by the U.S. Department of Transportation.  There can be no assurance
that   additional  or  modified   regulations   relating  to  the   manufacture,
transportation,  storage,  use and disposal of materials used to manufacture our
batteries or restricting  disposal of batteries will not be imposed or how these
regulations will affect us or our customers.

      In connection with our  purchase/lease of our Newark, New York facility in
1998, a consulting firm performed a Phase I and II Environmental Site Assessment
which revealed the existence of contaminated soil and ground water around one of
our buildings.  We retained an engineering firm which estimated that the cost of
remediation should be in the range of $230,000. This cost, however, is merely an
estimate and the cost may in fact be much higher.  In February  1998, we entered
into an agreement with a third party which provides that we and this third party
will retain an environmental  consulting firm to conduct a supplemental Phase II
investigation to verify the existence of the contaminants and further


                                      -6-


delineate  the nature of the  environmental  concern.  The third party agreed to
reimburse  us for fifty  percent  of the cost of  correcting  the  environmental
concern on the Newark property.  Test sampling occurred in the fourth quarter of
fiscal  2001 and the  engineering  report  was  submitted  to the New York State
Department of Environmental  Conservation  (NYSDEC) for review.  NYSDEC reviewed
the report and, in January 2002, recommended additional testing. We responded by
submitting a proposed work plan to NYSDEC, which was approved by NYSDEC in April
2002.  We are now  soliciting  proposals  from  engineering  firms  to  complete
remedial work contained in the work plan, and it is unknown at this time whether
the final cost to remediate will be in the range of the original estimate, given
the  passage  of  time.  The  ultimate  resolution  of this  matter  may  have a
significant  adverse  impact on the results of our  operations  in the period in
which it is resolved.  Furthermore,  we may face claims resulting in substantial
liability which would have a material adverse effect on our business,  financial
condition  and the results of our  operations in the period in which such claims
are resolved.

Limited Sources of Supply

      Certain  materials we use in our products are available only from a single
or a  limited  number  of  suppliers.  Additionally,  we may  elect  to  develop
relationships  with a single or limited  number of suppliers for materials  that
are  otherwise  generally  available.   Although  we  believe  that  alternative
suppliers  are  available  to supply  materials  that  could  replace  materials
currently  used by us and that, if  necessary,  we would be able to redesign our
products to make use of such  alternatives,  any interruption in our supply from
any supplier  that serves as our sole source could delay  product  shipments and
have a material adverse effect on our business,  financial condition and results
of operations.  Although we have experienced interruptions of product deliveries
by sole source suppliers,  these  interruptions  have not had a material adverse
effect on our business, financial condition and results of operations. We cannot
guarantee  that we will  not  experience  a  material  interruption  of  product
deliveries from sole source suppliers.

Dependence on Proprietary Technologies

      Our  success  depends  more  on the  knowledge,  ability,  experience  and
technological  expertise of our  employees  than on the legal  protection of our
patents and other proprietary  rights.  We claim  proprietary  rights in various
unpatented technologies,  know-how, trade secrets and trademarks relating to our
products  and  manufacturing  processes.  We  cannot  guarantee  the  degree  of
protection these various claims may or will afford, or that our competitors will
not  independently   develop  or  patent  technologies  that  are  substantially
equivalent or superior to our technology.  We protect our proprietary  rights in
our  products  and  operations  through   contractual   obligations,   including
nondisclosure  agreements  with certain  employees,  customers,  consultants and
strategic  partners.  There can be no assurance  as to the degree of  protection
these  contractual  measures may or will afford.  We, however,  have had patents
issued and patent  applications  pending in the U.S. and elsewhere.  However, we
cannot guarantee (1) that patents will be issued from any pending  applications,
or that the claims  allowed  under any  patents  will be  sufficiently  broad to
protect  our  technology,  (2)  that  any  patents  issued  to us  will  not  be
challenged,  invalidated or circumvented, or (3) as to the degree or adequacy of
protection  any patents or patent  applications  may or will  afford.  If we are
found to be infringing  third party  patents,  there can be no assurance that we
will be able to obtain  licenses  with  respect to such  patents  on  acceptable
terms, if at all. Our failure to obtain  necessary  licenses could delay product
shipment or the  introduction  of new  products,  and costly  attempts to design
around such patents could foreclose the development,  manufacture or sale of our
products.


                                      -7-


Dependence on Technology Transfer Agreements

      Our research and development of advanced  rechargeable  battery technology
and products utilizes internally-developed  technology,  acquired technology and
certain patents and related technology licensed by us pursuant to non-exclusive,
technology transfer  agreements.  There can be no assurance that our competitors
will  not  develop,  independently  or  through  the use of  similar  technology
transfer  agreements,  rechargeable  battery  technology  or  products  that are
substantially  equivalent or superior to the technologies and products currently
under research and development by us.

Risks Related to China Joint Venture Program

      In  July  1992,  we  entered  into  several   agreements  related  to  the
establishment  of  a  manufacturing  facility  in  Changzhou,   China,  for  the
production and distribution in and from China of 2/3A lithium primary batteries.
Changzhou  Ultra Power Battery Co.,  Ltd., a company  organized in China ("China
Battery"),  purchased  from  us  certain  technology,  equipment,  training  and
consulting  services  relating to the design and operation of a lithium  battery
manufacturing  plant.  China  Battery  was  required to pay  approximately  $6.0
million to us over the first two years of the agreement,  of which approximately
$5.6 million has been paid.  We have been  attempting to collect the balance due
under this  contract.  China Battery has  indicated  that it will not make these
payments  until  certain  contractual  issues have been  resolved.  Due to China
Battery's  questionable  willingness  to pay,  we wrote off in  fiscal  1997 the
entire balance owed to us as well as our investment aggregating $805,000.  Since
China Battery has not purchased  technology,  equipment,  training or consulting
services from us to produce batteries other than 2/3 A lithium batteries,  we do
not believe that China Battery has the capacity to become our competitor.  We do
not anticipate that the  manufacturing  or marketing of 2/3 A lithium  batteries
will be a  substantial  portion of our product line in the future.  However,  in
December 1997, China Battery sent to us a letter  demanding  reimbursement of an
unspecified  amount  of losses  they have  incurred  plus a refund  for  certain
equipment  that  we  sold to  China  Battery.  We  have  attempted  to  initiate
negotiations to resolve the dispute.  However, an agreement has not yet reached.
Although  China  Battery  has not taken any  additional  steps,  there can be no
assurance  that China  Battery will not further  pursue such a claim  which,  if
successful,  would have a material  adverse  effect on our  business,  financial
condition  and results of  operations.  We believe  that such a claim is without
merit.

Ability to Insure Against Losses

      Because certain of our primary batteries are used in a variety of security
and safety products and medical  devices,  we may be exposed to liability claims
if such a battery fails to function properly.  We maintain what we believe to be
sufficient  liability  insurance  coverage to protect against  potential claims;
however, there can be no assurance that the liability insurance will continue to
be available,  or that any such liability insurance would be sufficient to cover
any claim or claims.

Possibility of Warranty Claims

      We provide  warranties  for our various  products.  The  longest  warranty
duration is ten years,  which covers our 9-volt  battery  used in certain  smoke
detector  applications.  We  maintain  a  warranty  reserve  to cover  potential
warranty  claims.  We  cannot  guarantee,  however,  that the  reserves  will be
sufficient  to satisfy  warranty  claims made. In the event that we experience a
significant  rise in warranty  claims  made,  such action  could have a material
adverse  effect on our  business,  financial  condition  and the  results of our
operations.


                                      -8-


Possible Volatility of Stock Price

      Future   announcements   concerning  us  or  our  competitors,   including
technological innovations or commercial products,  litigation or public concerns
as to the safety or commercial  value of one or more of our products,  may cause
the market  price of our Common  Stock to  fluctuate  substantially  for reasons
which may be unrelated  to operating  results.  These  fluctuations,  as well as
general economic,  political and market conditions,  may have a material adverse
effect on the market price of our Common Stock.

Risk Related to Arthur Andersen's Role in Auditing Our Financial Statements

      Arthur Andersen LLP audited our annual  financial  statements and issued a
report,  dated August 16,  2001,  concerning  those  financial  statements.  Our
financial  statements and Arthur Andersen's report are incorporated by reference
into this Prospectus.  The Rochester,  New York office of Arthur Andersen, which
was primarily responsible for auditing our financial statements, is undergoing a
mandatory  employee force reduction and is expected to permanently  close in the
imminent  future.  Accordingly,  we are unable to obtain  the  consent of Arthur
Andersen to incorporate its report into this Prospectus. Our inability to obtain
Arthur  Andersen's  consent to incorporate  such report into this Prospectus may
prevent you from being able to recover  damages from Arthur  Andersen  under the
Securities Act of 1933. In particular, because of this lack of consent, you will
not be able to sue Arthur Andersen under Section  11(a)(4) of the Securities Act
for any untrue  statements of material fact contained in the report or financial
statements  audited by Arthur  Andersen or any failure to state a material  fact
required to be stated in the report or those financial  statements and therefore
your right of recovery under that section may be limited.

                           FORWARD-LOOKING STATEMENTS

      This  Prospectus,  including  information  contained in documents that are
incorporated  by  reference  in  this   Prospectus,   contains   forward-looking
statements,  as that term is defined by federal  securities laws, that relate to
the  financial  condition,  results of  operations,  plans,  objectives,  future
performance and business of Ultralife.  These statements are frequently preceded
by, followed by or include the words believes, expects,  anticipates,  estimates
or similar expressions.

      We have based these forward-looking statements on our current expectations
and projections about future events. The statements contained in this Prospectus
relating to matters that are not historical facts are forward-looking statements
that involve risks and  uncertainties,  including future demand for our products
and services,  the  successful  commercialization  of our advanced  rechargeable
batteries, general economic conditions, government and environmental regulation,
competition and customer  strategies,  technological  innovations in the primary
and  rechargeable  battery  industries,  changes  in our  business  strategy  or
development plans,  capital deployment,  business  disruptions,  including those
caused by fire,  raw  materials,  supplies  and other  risks and  uncertainties,
certain of which are beyond our control.

      In addition to these  risks,  in the section of this  Prospectus  entitled
"Risk Factors",  we have summarized a number of the risks and uncertainties that
could affect the actual outcome of the  forward-looking  statements  included in
this   Prospectus.   We  advise  you  not  to  place  undue  reliance  on  these
forward-looking  statements in light of the material risks and  uncertainties to
which  they are  subject.  Should  one or more of these  risks or  uncertainties
materialize,  or should underlying  assumptions prove incorrect,  actual results
may differ  materially  from those described  herein as  anticipated,  believed,
estimated or expected.  We undertake no obligation to publicly  update or revise
any forward-looking statements,  whether as a result of new information,  future
events or otherwise.

                                 USE OF PROCEEDS

      We will not  receive  any of the  proceeds  from the sale of the shares of
Common Stock by the selling  stockholders.  We have agreed to bear all expenses,
other than  selling  commissions  and fees and  expenses  of  counsel  and other
advisors to the selling stockholders, in connection with the registration of the
shares being offered.

                              SELLING STOCKHOLDERS

      The  following  Table A sets  forth the  number of shares of Common  Stock
owned by each of the selling  stockholders  who  purchased  shares of our Common
Stock in our recent private  placement.  None of these selling  stockholders has
had a material  relationship with us within the past three years other than as a
result of the  ownership of our Common Stock.  Because the selling  stockholders
may offer all or some of the  Common  Stock  which  they  hold  pursuant  to the
offering  contemplated  by this  Prospectus,  and because there are currently no
agreements,  arrangements or  understandings  with respect to the sale of any of
the  shares,  no  estimate  can be given as to the amount of shares that will be
held by the selling  stockholders after completion of this offering.  The shares
offered  by this  Prospectus  may be  offered  from time to time by the  selling
stockholders named below or by pledgees, donees, transferees or other successors
in interest who receive the shares as a gift, partnership  distribution or other
non-sale related transfer.

                              PLAN OF DISTRIBUTION

      We will receive no proceeds from this offering. The shares offered by this
Prospectus  may be sold by the selling  stockholders  (including  those  holding
stock as a result of the future  conversion of the Debenture)  from time to time
in transactions in the over-the-counter market, in negotiated  transactions,  or
in a combination  of such methods of sale, at fixed prices which may be changed,
at market prices prevailing at the time of sale, at prices related to prevailing
market prices or at negotiated prices. The selling stockholders (including those
holding stock as a result of the future  conversion of the Debenture) may effect
such transactions by selling the shares to or through  broker-dealers,  and such
broker-dealers may receive compensation in the form of discounts, concessions or
commissions  from the selling  stockholders  (including those holding stock as a
result of the future  conversion of the Debenture)  and/or the purchasers of the
shares  for whom such  broker-dealers  may act as agents or to whom they sell as
principals,  or  both.  This  compensation  might  be  in  excess  of  customary
commissions.  The shares we are  offering  may be sold  either  pursuant to this
Registration  Statement  or  pursuant  to Rule 144  issued  by the SEC under the
Securities Act of 1933.


                                      -11-


      In  order to  comply  with  the  securities  laws of  certain  states,  if
applicable,  the  shares  will  be  sold  in  such  jurisdictions  only  through
registered or licensed  brokers or dealers.  In addition,  in certain states the
shares may not be sold unless they have been registered or qualified for sale in
the applicable  state or an exemption  from the  registration  or  qualification
requirement is available and is complied with.

      The selling stockholders (including those holding stock as a result of the
future  conversion  of the  Debenture)  and any  broker-dealers  or agents  that
participate  with the selling  stockholders  (including those holding stock as a
result of the future  conversion of the  Debenture) in the  distribution  of the
shares may be deemed to be  "underwriters"  within the meaning of the Securities
Act of 1933, and any  commissions  received by them and any profit on the resale
of the shares purchased by them may be deemed to be underwriting  commissions or
discounts under federal law.

      Under applicable federal rules and regulations,  any person engaged in the
distribution of our Common Stock may not simultaneously  engage in market making
activities  with respect to our Common  Stock for a period of two business  days
prior  to the  commencement  of such  distribution.  In  addition,  and  without
limiting the foregoing,  each selling  stockholder will be subject to applicable
provisions of the Securities  Exchange Act of 1934 and the rules and regulations
of the SEC  promulgated  thereunder.  These rules include,  without  limitation,
Rules  10b-6 and  10b-7,  which may limit the timing of  purchases  and sales of
shares of our Common Stock by the selling stockholders  (including those holding
stock as a result of the future conversion of the Debenture).

                                  LEGAL MATTERS

      The validity of the  securities  offered hereby will be passed upon for us
by Harter, Secrest & Emery LLP, Rochester, New York.

                                     EXPERTS

      Our consolidated  balance sheets as of June 30, 2000 and June 30, 2001 and
our consolidated statements of income, retained earnings, and cash flow for each
of the three years in the period ended June 30, 2001  incorporated  by reference
in this Prospectus,  have been incorporated  herein in reliance on the report of
Arthur  Andersen LLP,  independent  accountants,  given on the authority of that
firm as experts in accounting and auditing.

      After  reasonable  efforts,  we  have  not  been  able  to  obtain  Arthur
Andersen's  written consent to the inclusion of their report in this Prospectus,
and we have dispensed with the  requirement to file their consent in reliance on
Rule 437a, as  promulgated  under the  Securities  Act of 1933.  Because  Arthur
Andersen has not  consented to the  inclusion of its report in this  Prospectus,
your  ability to assert  claims  against  Arthur  Andersen  may be  limited.  In
particular,  because of this lack of consent, you will not be able to sue Arthur
Andersen under Section 11(a)(4) of the Securities Act for any untrue  statements
of  material  fact  contained  in the  financial  statements  audited  by Arthur
Andersen  or any  omissions  to state a material  fact  required to be stated in
those  financial  statements  and  therefore  your right of recovery  under that
section may be limited.

                       WHERE YOU CAN FIND MORE INFORMATION

      No  person  has been  authorized  to give any  information  or to make any
representations other than those contained in this Prospectus in connection with
this offering of our Common Stock.  If any such  information or  representations

circumstances,  create any implication that information  herein is correct as of
any time  subsequent to the date hereof.  This Prospectus does not constitute an
offer to sell or a  solicitation  of an offer to buy any security other than the
Common Stock covered by this  Prospectus,  nor does it constitute an offer to or

Exchange  Commission  (the "SEC").  You may inspect and copy any reports,  proxy

with  all  amendments  and  exhibits,  referred  to in  this  Prospectus  as the
"Registration  Statement")  under the Securities Act of 1933 with respect to the
Common  Stock we are  offering.  This  Prospectus  does not  contain,  nor is it
required  to  contain,  all of the  information  set  forth in the  Registration
Statement,  certain parts of which are omitted in accordance  with the rules and

Act may be permitted to directors,  officers of persons  controlling us pursuant
to the  foregoing  provisions,  we have been informed that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in such Act and is therefore unenforceable.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

      With respect to indemnification of directors and officers,  Section 145 of
the Delaware General  Corporation Law ("DGCL") provides that a corporation shall
have the power to indemnify any person who was or is a party or is threatened to
be  made a  party  to any  threatened,  pending  or  completed  action,  suit or
proceeding, whether civil, criminal, administrative or investigative (other than
an action by or in the right of the  corporation) by reason of the fact that the
person is or was a director,  officer, employee or agent of the corporation,  or
is or was serving at the  request of the  corporation  as a  director,  officer,
employee or agent of another corporation,  partnership,  joint venture, trust or
other enterprise, against expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by the person in
connection  with such action,  suit or  proceeding,  if the person acted in good
faith and in a manner the person reasonably  believed to be in or not opposed to
the best interests of the corporation,  and, with respect to any criminal action
or  proceeding,  had no  reasonable  cause to believe the  person's  conduct was
unlawful.  Under this provision of the DGCL, the termination of any action, suit
or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo
contendere or its equivalent,  shall not, of itself,  create a presumption  that
the person did not act in good faith and in a manner which the person reasonably
believed to be in or not opposed to the best interests of the  corporation,  and
with respect to any  criminal  action or  proceeding,  had  reasonable  cause to
believe that the person's conduct was unlawful.

      Furthermore,  the DGCL provides that a corporation shall have the power to
indemnify  any person who was or is a party or is  threatened to be made a party
to any threatened, pending or completed action or suit by or in the right of the
corporation  to procure a  judgment  in its favor by reason of the fact that the
person is or was a director,  officer, employee or agent of the corporation,  or
is or was serving at the  request of the  corporation  as a  director,  officer,
employee or agent of another corporation,  partnership,  joint venture, trust or
other  enterprise,  against  expenses  (including  attorneys' fees) actually and
reasonably  incurred by the person in connection  with the defense or settlement
of such  action or suit if the  person  acted in good  faith and in a manner the
person reasonably  believed to be in or not opposed to the best interests of the
corporation and except that no  indemnification  shall be made in respect of any
claim,  issue or matter as to which such person  shall have been  adjudged to be
liable  to the  corporation  unless  and only to the  extent  that the  Court of
Chancery or the court in which such action or suit was brought  shall  determine
upon application that,  despite the adjudication of liability but in view of all
the circumstances of the case, such person is fairly and reasonably  entitled to
indemnity  for such  expenses  which the Court of  Chancery  or such other court
shall deem proper.


                                      II-1


      The Registrant's  Restated  Certificate of Incorporation (the "Certificate
of  Incorporation")   and  By-laws,  as  amended  (the  "By-laws")  provide  for
limitation of the liability of directors to the Registrant and its  stockholders
and for  indemnification  of  directors,  officers,  employees and agents of the
Registrant, respectively, to the maximum extent permitted by the DGCL.

      The Certificate of Incorporation provides that directors are not liable to
the  Registrant  or its  stockholders  for  monetary  damages  for  breaches  of
fiduciary  duty as a director,  except for  liability  (a) for any breach of the
director's duty of loyalty to the Registrant or its  stockholders,  (b) for acts
or  omissions  not in good faith or that  involve  intentional  misconduct  or a
knowing  violation  of law, (c) for dividend  payments or stock  repurchases  in
violation of Delaware  law, or (d) for any  transaction  from which the director
derived any improper personal benefit.

      The By-laws include  provisions by which the Registrant will indemnify its
officers and directors and other persons against expenses,  judgments, fines and
amounts  paid in  settlement  with respect to  threatened,  pending or completed
suits or proceedings  against such persons by reason of serving or having served
the Registrant as officers, directors or in other capacities, except in relation
to matters with respect to which such persons  shall be  determined  not to have
acted in good faith,  lawfully or in the best interests of the Registrant.  With
respect to matters to which the  Registrant's  officers,  directors,  employees,
agents or other  representatives  are  determined to be liable for misconduct or
negligence  in  the  performance  of  their  duties,  the  By-laws  provide  for
indemnification  only to the extent  that the  Registrant  determines  that such
person  acted in good faith and in a manner he  reasonably  believed to be in or
not opposed to the best interests of the Registrant.

ITEM 17. UNDERTAKINGS

      The  undersigned  Registrant  hereby  undertakes  (subject  to the proviso
contained in Item 512(a) of Regulation S-K):

      (1) To file,  during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:

      (i)  to  include  any  Prospectus  required  by  section  10(a)(3)  of the
Securities  Act of 1933;  (ii) to reflect in the  Prospectus any facts or events
arising  after the  effective  date of the  Registration  Statement (or the most
recent  post-effective   amendment  thereof)  which,   individually  or  in  the
aggregate,  represent a fundamental  change in the  information set forth in the
Registration Statement.  Notwithstanding the foregoing, any increase or decrease
in volume of securities offered (if the total dollar value of securities offered
would not exceed that which was  registered)  and any deviation  from the low or
high end of the estimated  maximum  offering range may be reflect in the form of
Prospectus  filed  with  the  Commission  pursuant  to Rule  424(b)  if,  in the
aggregate,  the  changes in volume and price  represent  no more than 20 percent
change in the maximum aggregate  offering price set forth in the "Calculation of
Registration Fee" table in the effective registration statement; and

      (iii) to include  any  material  information  with  respect to the plan of
distribution  not  previously  disclosed  in the  Registration  Statement or any
material change to such information in the Registration Statement.

      (2)  That,  for  the  purpose  of  determining  any  liability  under  the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

      (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

      The  undersigned  Registrant  hereby  undertakes  that,  for  purposes  of
determining  any liability  under the Securities Act of 1933, each filing of the
Registrant's  annual  report  pursuant to Section  13(a) or Section 15(d) of the
Securities  Exchange  Act of  1934  that is  incorporated  by  reference  in the
Registration  Statement  shall  be  deemed  to be a new  registration  statement
relating to the securities offered therein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

      The undersigned Registrant hereby undertakes to supplement the Prospectus,
after  expiration of the  subscription  period,  to set forth the results of the
subscription offer, the transactions by the underwriters during the subscription
period,   the  amount  of  unsubscribed   securities  to  be  purchased  by  the
underwriters,  and the terms of any subsequent reoffering thereof. If any public
offering by the  underwriters  is to be made on terms  different  from those set
forth on the cover page of the Prospectus,  a  post-effective  amendment will be
filed to set forth the terms of such offering.

      Insofar as  indemnification  for liabilities  arising under the Securities
Act of 1933 may be permitted to directors,  officers and controlling  persons of
the  Registrant  pursuant  to  the  foregoing  provisions,   or  otherwise,  the
Registrant  has been advised that in the opinion of the  Securities and Exchange
Commission  such  indemnification  is against  public policy as expressed in the
Securities  Act of 1933 and is,  therefore,  unenforceable.  In the event that a
claim for  indemnification  against such liabilities  (other than the payment by
the  Registrant  of  expenses  incurred  or  paid  by  a  director,  officer  or
controlling  person of the Registrant in the  successful  defense of any action,
suit or proceeding) is asserted by such director,  officer or controlling person
in connection with the securities being registered,  the Registrant will, unless
in the  opinion  of its  counsel  the matter  has been  settled  by  controlling
precedent,  submit to a


                                      -3-


court of appropriate  jurisdiction the question whether such  indemnification by
it is against  public policy as expressed in the Securities Act of 1933 and will
be governed by the final adjudication of such issue.

      The  undersigned  registrant  hereby  undertakes to deliver or cause to be
delivered  the  Prospectus,  to each  person to whom the  Prospectus  is sent or
given,  the latest annual report,  to security  holders that is  incorporated by
reference  in  the  Prospectus  and  furnished   pursuant  to  and  meeting  the
requirements  of Rule 14a-3 or Rule 14c-3 under the Exchange  Act of 1934;  and,
where  interim  financial  information  required to be presented by Article 3 of
Regulation S-X is not set forth in the  Prospectus,  to deliver,  or cause to be
delivered  to each person to whom the  Prospectus  is sent or given,  the latest
quarterly report that is specially incorporated by referred in the Prospectus to
provide such interim financial information.


                                      -4-


                                   SIGNATURES

      Pursuant to the requirements of the Securities Act of 1933, the Registrant
certifies  that is has  reasonable  grounds to believe  that it meets all of the
requirements  for  filing  on Form S-3 and has  duly  caused  this  Registration
Statement  to be  signed  on its  behalf  by  the  undersigned,  thereunto  duly
authorized  in the City of Newark,  State of New York, on this 21st day of June,
