                            ULTRALIFE BATTERIES, INC.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
       (Dollar Amounts in Thousands - Except Share and Per Share Amounts)
                                   (unaudited)
--------------------------------------------------------------------------------

1.    BASIS OF PRESENTATION

            The accompanying unaudited condensed consolidated financial
      statements have been prepared in accordance with generally accepted
      accounting principles for interim financial information and with the
      instructions to Article 10 of Regulation S-X. Accordingly, they do not
      include all of the information and footnotes for complete financial
      statements. In the opinion of management, all adjustments (consisting of
      normal recurring accruals and adjustments) considered necessary for a fair
      presentation of the condensed consolidated financial statements have been
      included. Results for interim periods should not be considered indicative
      of results to be expected for a full year. Reference should be made to the
      consolidated financial statements contained in the Company's Form 10-K for
      the twelve-month period ended December 31, 2003.

            The Company's monthly closing schedule is a weekly-based cycle as
      opposed to a calendar month-based cycle. While the actual dates for the
      quarter-ends will change slightly each year, the Company believes that
      there are not any material differences when making quarterly comparisons.

2.    WRITE-OFF OF UTI INVESTMENT AND NOTE RECEIVABLE

            In June 2004, the Company recorded a $3,951 non-cash, non-operating
      charge related to the Company's ownership interest in Ultralife Taiwan,
      Inc. ("UTI") that consisted of a write-off of its $2,401 note receivable
      from UTI, including accrued interest, and the book value of its $1,550
      equity investment in UTI. The Company decided to record this charge due to
      recent events that have caused increasing uncertainty over UTI's near-term
      financial viability, including a failure by UTI to meet commitments made
      to the Company and its other creditors to secure additional financial
      support before July 1, 2004. Based on these factors, and UTI's operating
      losses over several years, the Company's investment has had an other than
      temporary decline in fair value and the Company believes that the
      probability of being reimbursed for the note receivable is nominal. The
      Company continues to hold a 9.2% equity interest in UTI, and it is working
      with UTI to help it through its financial difficulties in an effort to
      ensure a satisfactory outcome for all parties involved. The Company does
      not believe the write-off poses a risk to its current operations or future
      growth prospects because UTI continues to manufacture product for it and
      the Company has taken steps to establish alternate sources of supply.

3.    EARNINGS (LOSS) PER SHARE

            Basic earnings per share are calculated by dividing net income by
      the weighted average number of common shares outstanding during the
      period. Diluted earnings per share are calculated by dividing net income,
      adjusted for interest on convertible securities, by potentially dilutive
      common shares, which include stock options, warrants and convertible
      securities.

            Net loss per share is calculated by dividing net loss by the
      weighted average number of common shares outstanding during the period.
      The impact of conversion of dilutive securities, such as stock options and
      warrants, are not considered where a net loss is reported as the inclusion
      of such securities would be anti-dilutive. As a result, basic loss per
      share is the same as diluted loss per share.


                                       6


            The computation of basic and diluted earnings per share is
      summarized as follows:

            The Company also had the equivalent of 1,056,880 options and
      warrants outstanding for the three-month period ended June 26, 2004 which
      were not included in the computation of diluted EPS because these
      securities would have been anti-dilutive for that period.

4.    STOCK-BASED COMPENSATION

            The Company has various stock-based employee compensation plans. The
      Company applies Accounting Principles Board (APB) Opinion No. 25,
      "Accounting for Stock Issued to Employees," and related interpretations
      which require compensation costs to be recognized based on the difference,
      if any, between the quoted market price of the stock on the grant date and
      the exercise price. As all options granted to employees under such plans
      had an exercise price at least equal to the market value of the underlying
      common stock on the date of grant, and given the fixed nature of the
      equity instruments, no stock-based employee compensation cost is reflected
      in net (loss) income. The effect on net (loss) income and (loss) earnings
      per share if the Company had applied the fair value recognition provisions
      of Statement of Financial Accounting Standards ("SFAS") No. 148,
      "Accounting for Stock-Based Compensation - Transition and Disclosure, an
      Amendment of SFAS No. 123", to stock-based employee compensation is as
      follows:

8.    DEBT

            As of June 26, 2004, the Company had $867 outstanding under the term
      loan component of its credit facility with its primary lending bank, and
      had $4,209 of borrowings outstanding under the revolver component of the
      credit facility. The Company's additional borrowing capacity under the
      revolver component of the credit facility as of June 26, 2004 was
      approximately $5,900, net of outstanding letters of credit of $3,600. At
      June 26, 2004, the Company's net worth was $41,091, compared to the debt
      covenant requiring a minimum net worth of approximately $22,406. (See Note
      13 for information on the Company's new credit facility.)

            As of June 26, 2004, the Company's wholly-owned U.K. subsidiary,
      Ultralife Batteries (UK) Ltd., had approximately $345 outstanding under
      its revolving credit facility with a commercial bank in the U.K. This
      credit facility provides the Company's U.K. operation with additional
      financing flexibility for its working capital needs. Any borrowings
      against this credit facility are collateralized with that company's
      outstanding accounts receivable balances. There was approximately $476 in
      additional borrowing capacity under this credit facility as of June 26,
      2004.

9.    INCOME TAXES

            The liability method, prescribed by SFAS No. 109, "Accounting for
      Income Taxes", is used in accounting for income taxes. Under this method,
      deferred tax assets and liabilities are determined based on differences
      between financial reporting and tax bases of assets and liabilities and
      are measured using the enacted tax rates and laws that may be in effect
      when the differences are expected to reverse. The Company recorded an
      income tax expense of $79 for the six months ended June 26, 2004 relating
      to alternative minimum tax calculations.

            As of December 31, 2003, the Company had foreign and domestic net
      operating loss carryforwards totaling approximately $76,829 that are
      available to reduce future taxable income. The Company has not reported a
      deferred tax asset on its Consolidated Balance Sheet due to prior
      operating losses. It is reasonably possible the Company's profitability in
      2003 and 2004 would result in the recognition of a deferred tax asset
      during 2004. The Company has determined that a change in ownership as
      defined under Internal Revenue Code Section 382 occurred during the fourth
      quarter of 2003. As a result, the net operating loss carryforwards will be
      subject to an annual limitation, currently estimated to be in the range of
      approximately $14,000 to $18,000. Such a limitation could result in the
      possibility of a cash outlay for income taxes in a future year when
      earnings exceed the amount of NOLs that can be used by the Company.

10.   COMMITMENTS AND CONTINGENCIES

            As of June 26, 2004, the Company had $51 in restricted cash in
      support of a corporate credit card account.

            As of June 26, 2004, the Company had open capital commitments to
      purchase approximately $2,071 of production machinery and equipment.

            The Company estimates future costs associated with expected product
      failure rates, material usage and service costs in the development of its
      warranty obligations. Warranty reserves, included in other current
      liabilities on the Company's Consolidated Condensed Balance Sheet, are
      based on historical experience of warranty claims and generally will be
      estimated as a percentage of sales over the warranty period. In the event
      the actual results of these items differ from the estimates, an adjustment
      to the warranty obligation would be recorded. Changes in the Company's
      product warranty liability during the first six months of 2004 were as
      follows:

             Balance at December 31, 2003                         $ 278
             Accruals for warranties issued                         237
             Settlements made                                      (147)
                                                                  -----
             Balance at June 26, 2004                             $ 368
                                                                  =====

            The Company is subject to legal proceedings and claims which arise
      in the normal course of business. The Company believes that the final
      disposition of such matters will not have a material adverse effect on the
      financial position or results of operations of the Company.

            In conjunction with the Company's purchase/lease of its Newark, New
      York facility in 1998, the Company entered into a payment-in-lieu of tax
      agreement which provides the Company with real estate tax concessions upon
      meeting certain conditions. In connection with this agreement, 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 the buildings. The Company retained an engineering firm which
      estimated that the cost of remediation should be in the range of $230.
      This cost, however, is merely an estimate and the cost may in fact be much
      higher. In February, 1998, the


                                       10


      Company entered into an agreement with a third party, which provides that
      the Company 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 delineate the nature of the
      environmental concern. The third party agreed to reimburse the Company for
      fifty percent (50%) of the cost of correcting the environmental concern on
      the Newark property. The Company has fully reserved for its portion of the
      estimated liability. Test sampling was completed in the spring of 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. The Company
      submitted a work plan to NYSDEC in October 2003, which was approved
      shortly thereafter. The Company sought proposals from engineering firms to
      complete the remedial work outlined in the work plan. A firm was selected
      to perform the tasks associated with the remediation activities, which
      were completed in December 2003. The test results were then forwarded to
      NYSDEC for comment. NYSDEC responded to the Company in March 2004
      requesting a report summarizing the data, findings, discussions and
      conclusions. The report has been submitted to NYSDEC who will review and
      make recommendations as to whether additional remediation is required.
      Because the Company believes that the source of the contamination has been
      removed, NYSDEC recommended that the Company conduct quarterly monitoring
      of the groundwater for one year. The Company believes that the final cost
      to remediate will not exceed the original estimate. The Company awaits
      final comments from the NYSDEC and will begin the additional sampling upon
      approval of the conclusions stated in the report. Because this is a
      voluntary remediation, there is no requirement for the Company to complete
      the project within any specific time frame. The ultimate resolution of
      this matter may have a significant adverse impact on the results of
      operations in the period in which it is resolved. Furthermore, the Company
      may face claims resulting in substantial liability which could have a
      material adverse effect on the Company's business, financial condition and
      the results of operations in the period in which such claims are resolved.

            A retail end-user of a product manufactured by one of Ultralife's
      customers (the "Customer") has made a claim against the Customer wherein
      it is asserted that the Customer's product, which is powered by an
      Ultralife battery, does not operate according to the Customer's product
      specification. No claim has been filed against Ultralife. However, in the
      interest of fostering good customer relations, in September 2002,
      Ultralife agreed to lend technical support to the Customer in defense of
      its claim. The claim between the end-user and the Customer has now been
      settled. Ultralife has renewed its commitment to the Customer to honor its
      warranty by replacing any batteries that may be determined to be
      defective. In the event a claim is filed against Ultralife and it is
      ultimately determined that Ultralife's product was defective, replacement
      of batteries to this Customer or end-user may have a material adverse
      effect on the Company's financial position and results of operations.

11.   BUSINESS SEGMENT INFORMATION

            The Company reports its results in three operating segments: Primary
      Batteries, Rechargeable Batteries, and Technology Contracts. The Primary
      Batteries segment includes 9-volt, cylindrical and various other
      non-rechargeable specialty batteries. The Rechargeable Batteries segment
      includes the Company's lithium polymer and lithium ion rechargeable
      batteries. The Technology Contracts segment includes revenues and related
      costs associated with various government and military development
      contracts. The Company looks at its segment performance at the gross
      margin level, and does not allocate research and development or selling,
      general and administrative costs against the segments. All other items
      that do not specifically relate to these three segments and are not
      considered in the performance of the segments are considered to be
      Corporate charges.

12.   FIRES AT MANUFACTURING FACILITIES

            In May 2004 and June 2004, the Company experienced two fires that
      damaged certain inventory and property at its facilities. The May 2004
      fire occurred at the Company's U.S. facility and was caused by cells that
      shorted out when a forklift truck accidentally tipped the cells over in an
      oven in an enclosed area. Certain inventory, equipment and a small portion
      of the building where the fire was contained were damaged. The June 2004
      fire happened at the Company's U.K. location and mainly caused damage to
      various inventory and the U.K. company's leased facility. The fire was
      contained mainly in a bunkered, non-manufacturing area designed to store
      various material, and there was additional smoke and water damage to the
      facility and its contents. It is unknown how the U.K. fire was started.
      The fires caused relatively minor disruptions to the production
      operations, and had no impact on the Company's ability to meet customer
      demand during the quarter.

            The Company maintains replacement cost insurance on the property and
      equipment it owns or rents, with relatively low deductibles. The total of
      the two losses related to company-owned assets, including expenditures
      required to repair and clean up the facilities, is expected to be in the
      range of $2,000. The Company is working closely with the insurance
      companies on these matters, and it expects to be fully reimbursed by the
      insurance companies for these losses. The impacts on the Consolidated
      Statement of Operations and the net cash outflows from the Company are
      expected to be negligible. At June 26, 2004, the Company's prepaid and
      other current assets on its Consolidated Balance Sheet included a
      receivable from insurance companies for approximately $800 for equipment
      losses, inventory losses and clean-up costs incurred to date.

13.   SUBSEQUENT EVENT - NEW CREDIT FACILITY

            On June 30, 2004, the Company closed on a new secured $25,000 credit
      facility, comprised of a five-year $10,000 term loan component and a
      three-year $15,000 revolving credit component. This agreement replaces the
      Company's $15,000 credit facility that expired on the same date.

            On June 30, 2004, the Company drew down the full $10,000 term loan.
      The proceeds of the term loan, which is to be repaid in equal monthly
      installments over five years, are to be used for the retirement of
      outstanding debt and capital expenditures. Availability under the
      revolving credit component is subject to a debt to earnings ratio, whereas
      availability under the previous facility was limited by various asset
      values. The lenders of the new credit facility are JP Morgan Chase Bank
      and Manufacturers and Traders Trust Company, with JP Morgan Chase Bank
      acting as the administrative agent.

            On July 1, 2004, the Company entered into an interest rate swap
      arrangement to be effective on August 2, 2004, related to the $10,000 term
      loan, in order to take advantage of historically low interest rates. The
      Company received a fixed rate of interest in exchange for a variable rate.
      The swap rate received was 3.98% for five years and will be adjusted
      accordingly for a Eurodollar spread incorporated in the agreement, which
      is dependent upon a debt to earnings ratio within a predetermined grid. At
      July 1, 2004, the total adjusted rate of interest that the Company will
      pay on the outstanding portion of the $10,000 term loan was 5.23%.
