Ultralife Batteries, Inc. Receives $2.7 Million in Orders for Military Batteries

      Newark, New York - (June 12, 2003) - Ultralife Batteries, Inc. (NASDAQ:
ULBI) today announced orders valued at approximately $2.7 million from two of
its U.S. battery distributors for its BA-5390/U lithium military battery.
Shipments have begun and are expected to be completed by August.

      Nancy Naigle, Ultralife's vice president of sales & marketing, said, "Our
distributor business has been expanding rapidly and we are pleased to be able to
supply our key distributors with this popular battery for sale to military
installations in their territories. We anticipate continued growth in this sales
channel."

      John Kavazanjian, Ultralife's president and chief executive officer, said,
"These orders further enhance our penetration into an important distribution
market that serves military bases throughout the U.S. and further solidifies the
market demand for our products."

      The BA-5390/U is a lithium/manganese dioxide primary (non-rechargeable)
battery with 50 percent more energy than the alternative 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 70 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 military
organizations.
