       Company's 9-Volt Lithium Batteries To Be Marketed Under Major Brand

Newark, New York - (May 19, 2003) - Ultralife Batteries, Inc. (NASDAQ: ULBI)
today announced the receipt of a multi-million dollar order from a major
consumer products company for a private-labeled version of its popular 9-volt
lithium battery. Production will begin this month for scheduled shipments
starting in June and extending throughout 2003.

John D. Kavazanjian, Ultralife's president and chief executive officer, said,
"This order, from a well-recognized consumer-brand company, represents a
significant accomplishment in our efforts to open new channels of distribution
for our products worldwide and will contribute to our $65 million revenue goal
for the year. We are extremely pleased and honored to have our battery
represented by a company known throughout the world for the high quality,
performance and brand recognition of its products."

Joseph N. Barrella, Ultralife's senior vice president of technology and new

a major achievement in the growth of our 9-volt product line. We look forward to
this relationship resulting in expansion in existing and new markets for this
