           Ultralife Batteries, Inc. Receives $1.4 Million Order for
                              HiRate Military Cells

Newark, New York - August 19, 2003 - Ultralife Batteries, Inc. (NASDAQ: ULBI),
today announced the receipt of an order valued at approximately $1.4 million for
its HiRate(R)D-size lithium cells from one of its U.S. battery assembly
customers, a prime contractor to the U.S. Army. Ultralife announced orders for
the same product from this customer in July, February and last October. The
cells are used in batteries for thermal imaging sights, which are mounted on
weapons. The batteries will be supplied to the U.S. Army Communications and
Electronics Command. Cell deliveries have begun and are expected to continue
through the first quarter of 2004.

John Kavazanjian, Ultralife's president and chief executive officer, said, "This
continued stream of orders, both from our battery assembly customers and the
U.S. Army, supports our ongoing effort to capitalize on the increasing demand
for our advanced batteries in the military market."

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.
