             Ultralife Batteries, Inc. Awarded $7.4 Million Battery
                      Contract by U.S. Defense Department


    NEWARK, N.Y.--(BUSINESS WIRE)--March 17, 2005--Ultralife
Batteries, Inc. (NASDAQ: ULBI) has been awarded a new production
contract for its BA-5390/U battery valued at approximately $7.4
million, by the U.S. Defense Department. This contract is independent
of the Next Gen II, Phase IV five-year battery contract for the
BA-5390 and four other rectangular military batteries, which the
company was awarded in December 2004. Deliveries under this $7.4
million contract are required to be completed by May 14.
    "This contract once again affirms Ultralife's position as the
leading supplier of lithium/manganese dioxide batteries to the U.S.
Military," said John D. Kavazanjian, Ultralife's president and chief
executive officer. "It also illustrates the military's commitment to
adopting lithium/manganese dioxide batteries. We are gratified that
this important customer continues to have confidence in Ultralife's
ability to deliver product under tight deadlines so that it has an
ongoing supply of BA-5390 batteries ahead of battery production under
the Next Gen II, Phase IV contract."
    Added Kavazanjian, "Deliveries under this contract are expected to
occur in March and April. A substantial portion of these deliveries
was anticipated in our first quarter revenue guidance. While we still
expect revenue of $18 million, due to the timing of the receipt of
this contract it is possible that some revenue may shift into the
second quarter. Our full year revenue estimate of 10% to 20% growth
over the $98.2 million we reported for 2004 remains unchanged."
    The BA-5390/U is a lithium/manganese dioxide 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 Command 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 military.
