Ultralife Batteries, Inc. Awarded $28 Million Army Battery Contract

Newark, New York - August 5, 2003 - Ultralife Batteries, Inc. (NASDAQ: ULBI)
today announced that it has been awarded its largest contract to date for its
BA-5390/U battery valued at $28 million, by the U.S. Army Communications
Electronics Command (CECOM). Shipments will begin in November and continue into
the first quarter of 2004.

This contract announcement is unrelated to the upcoming Next Gen II Phase IV,
5-year battery procurement for this and other battery types, in which Ultralife
plans to participate through the normal bidding process.

John D. Kavazanjian, Ultralife's president and chief executive officer, said,
"This order supports our goal of reaching new levels of production, increased
revenue and profitability both for this year and next. In addition, it further
strengthens the foundation for sustainable growth in the upcoming year."

Joseph N. Barrella, Ultralife's senior vice president of new business
development, said, "We are pleased with the magnitude of this order, which
reflects the Army's confidence in our technology and ability to produce, and
reaffirms the continuing and increasing demand for this battery."

The BA-5390/U is a lithium/manganese dioxide primary (non-rechargeable) battery,
and, with 50 percent more energy, is an alternative to the lithium/sulfur
dioxide BA-5590/U battery, the most widely used military battery in the U.S.
Armed Forces. The BA-5390/U is widely used to power more than 50 military
applications, such as the AN/PRC-119 SINCGARS (Single Channel Ground and
Airborne Radio System) and the Javelin Medium Anti-Tank Missile Control Launch
Unit. The BA-5390/U provides soldiers with the latest and best battery
technology in a cost effective manner. More energy in each battery provides
longer mission time with fewer batteries for soldiers to carry, and fewer
batteries to ship and dispose of, all of which reduce cost to the Army.
