ULTRALIFE BATTERIES, INC. ANNOUNCES RESULTS FOR QUARTER ENDED DECEMBER 31, 2002

           - Revenues Rise to $8.8 Million as Military Demand Grows -

Newark, NY, February 26, 2003 - Ultralife Batteries, Inc. (NASDAQ: ULBI) today
announced its preliminary, unaudited results for the period ended December 31,
2002. Consolidated revenues for the quarter were $8.8 million compared to $7.5
million for the same period a year ago. The increase was driven by initial
shipments of UBI5390 batteries to the U.S. military, higher 9-volt shipments and
stronger sales of HiRate(R) batteries, offset in part by lower sales of small
cylindrical batteries.

Consolidated gross margin for the three months ended December 31, 2002 improved
nearly $1.0 million to $0.8 million from a loss of $0.2 million in the prior
year. Rechargeable battery margins improved $0.8 million as a result of cost
savings actions made during the prior year and lower depreciation charges.
Primary battery margins rose $0.2 million from the year before as a result of
9-volt manufacturing efficiencies and higher sales volumes, offset in part by
start-up activity for high volume large cylindrical battery production and lower
small cylindrical battery sales.

The Company's operating loss for the quarter ended December 31, 2002 was $1.7
million compared with an operating loss of $3.3 million last year, reflecting
the gross margin improvement and lower operating costs.

This period represents the end of the Company's transition "year", a six-month
period, as it has changed its fiscal year-end from June 30 to December 31
effective as of December 31, 2002.

In October 2002, the Company sold a portion of its equity investment in
Ultralife Taiwan, Inc., reducing its ownership interest from approximately 30%
to approximately 11%. In exchange, the Company received total consideration of
$2.4 million in cash and the return of 700,000 shares of Ultralife common stock.
Previously, the Company had reported that it expected to record at least a $2.4
million non-operating gain on this transaction; however, because the accounting
issues are complex, the Company and its independent auditors have not yet
determined the appropriate accounting treatment of the Company's investment.
Since a final conclusion has not yet been reached, the results reported today do
not reflect any gain or loss on this transaction. It is likely that the Company
will be required to restate prior period financial results related to the
accounting for its equity ownership interest. These restatements would only
affect non-operating earnings. The Company does not expect the restatement to
affect prior period cash flows from operating activities. Once the accounting
treatment has been determined, the Company intends to issue a press release
reporting final audited statements.

"As expected, we resumed revenue growth in the December quarter with stronger demand for 9-volt batteries and improved order flow in our military business," said John Kavazanjian, president and chief executive officer of Ultralife Batteries. "Because of the higher sales volumes, gross margins continued to improve." Mr. Kavazanjian continued, "Ultralife is at an inflection point today with growing momentum in the business, as evidenced by the recent series of contract awards from both the U.S. and U.K. military. In addition, while much of our development efforts recently have been geared toward military applications, there are many commercial opportunities that we are targeting with our superior lithium manganese-dioxide chemistry. We are growing at a very rapid pace right now, and still expect to grow revenues at least 50% in 2003 and to be profitable. We're very excited about our long-term growth prospects."
