     Ultralife Batteries, Inc. Receives $4.2 Million U.S. Army Battery Order
    ------------------------------------------------------------------------

Newark, New York - October 15, 2003 - Ultralife Batteries,  Inc. (NASDAQ:  ULBI)
has received an order valued at  approximately  $4.2 million from the U.S.  Army
Communications  and  Electronics  Command  (CECOM)  for its  BA-5372/U  military
batteries. The order represents another production release under the $32 million
NextGen II, 5-year Small Cylindrical  Battery  contract,  which CECOM awarded to
Ultralife  in June  2002.  The  company  expects to  deliver  against  the order
throughout 2004.

John D. Kavazanjian,  Ultralife's  president and chief executive officer,  said,
"This year we have been  delivering  primarily  against  orders for the  BA-5372
unrelated to the NextGen II contract.  Today's order and the production releases
we received  from CECOM in August give us visibility  for  continued  profitable
revenue growth in 2004. We anticipate receiving  additional  production releases
under  the  NextGen  II  contract  in 2004 and over  the  remaining  life of the
contract."

NextGen II is CECOM's five-year  acquisition  strategy with production contracts
awarded to provide three types of primary  (non-rechargeable)  lithium-manganese
dioxide  batteries  to the U.S.  Army.  The  three  battery  types -  BA-5372/U,
BA-5367/U and BA-5368/U - comprise the Small  Cylindrical Cell Lithium Manganese
Dioxide  Battery Group. A major  objective of this  acquisition is to maintain a
domestic  production  base of a  sufficient  capacity to timely  meet  peacetime
demands and have the ability to surge quickly to meet deployment demands.

The  BA-5372/U  battery is used for memory backup  primarily for the  AN/PRC-119
MANPACK  Single  Channel  Ground and Airborne  Radio System  (SINCGARS),  and in
numerous other applications  including encryption and cryptographic devices, and
the Patriot Missile System.
