Ultralife Batteries, Inc. Receives $545,000 Order for HiRate Military Cells

Newark, New York - July 30, 2003 - Ultralife Batteries, Inc. (NASDAQ: ULBI),
today announced the receipt of an order valued at $545,000 for its
HiRate(TM)D-size lithium cells from one of its U.S. battery assembly customers,
a prime contractor to the U.S. Army. Ultralife previously announced orders from
this customer in February and last October. The contractor will assemble the
cells into military batteries to be supplied to the U.S. Army Communications and
Electronics Command (CECOM) for use in thermal weapon sights. Cell deliveries
are expected to be completed during the 3rd quarter.

John Kavazanjian, Ultralife's president and chief executive officer, said, "We
are very pleased to receive this order to supply our cells for use in a
critically important battery, and look forward to the continued growth of our
lithium technology in a wide variety of military applications."

Ultralife's D-size lithium-manganese dioxide primary (non-rechargeable) cells
provide significantly more energy than competitors' lithium-sulfur dioxide
cells. These cells are used in a wide range of military and industrial
applications where high energy, long shelf life, safety and high reliability are
required.
