                ULTRALIFE BATTERIES, INC. REPORTS SECOND QUARTER
          OPERATING INCOME OF $1.9 MILLION ON REVENUE OF $20.1 MILLION

     - Gross Profit Increases 50% on 30% Revenue Growth Over Prior Quarter -

Newark,  NY, August 7, 2003 - Ultralife  Batteries,  Inc.  (NASDAQ:  ULBI) today
reported  operating  income of $1.9 million on record  revenues of $20.1 million
for its second  quarter  ended June 28, 2003.  Net income was $2.1  million,  or
$0.16 per diluted  share,  including  $0.4  million of  non-cash,  non-operating
income from foreign  currency  translation  impacts  pertaining to  intercompany
loans. In addition,  the Company generated positive operating cash flow (defined
as operating income plus depreciation and amortization) of $2.7 million.

Revenues  for the  second  quarter  increased  134% to $20.1  million  from $8.6
million for the same  three-month  period in the prior year.  The $11.5  million
increase was driven by higher  shipments of the Company's  HiRate(R)  batteries,
notably the BA-5390  batteries,  which are used by military  organizations  in a
variety of communications and weapons systems.

Gross margin for the June 2003 quarter reached $4.7 million, or 24% of revenues,
compared  with $1.1 million,  or 13% of revenues,  in the same period a year ago
reflecting revenue growth and manufacturing efficiency  improvements.  Operating
expenses were $2.8 million,  consistent  with last year's level,  exclusive of a
$14.3  million  impairment  charge on certain  fixed  assets.  As a result,  the
Company  reported  operating  income of $1.9  million for the three months ended
June 28, 2003 compared to an operating  loss of $16.1 million in the prior year.
Net income amounted to $2.1 million, or $0.16 per diluted share, compared with a
net loss of $16.5 million, or $1.28 per share, for the same period a year ago.

Compared to the first  quarter  that ended March 29,  2003,  the second  quarter
gross margin grew 50% on a 30% revenue  gain,  and  operating  income  increased
three-fold from $0.6 million to $1.9 million.

For the first  six  months  of 2003,  revenues  reached  $35.5  million,  a 104%
increase  over the $17.4  million in the prior year.  This growth was  primarily
fueled by strong demand for HiRate batteries, in particular the BA-5390, as well
as higher 9-volt battery  shipments.  Operating income was $2.5 million compared
to an  operating  loss of $18.2  million in 2002 that  included a $14.3  million
asset impairment charge. Net income amounted to $2.5 million in the year-to-date
period in 2003,  or $0.19 per diluted  share,  compared with a net loss of $19.3
million in the same six-month period last year, or a loss of $1.52 per share.

"We set a goal at the beginning of this year to sustain  profitability  starting
in the first  quarter of 2003,  and we are  delivering,"  said Mr.  Kavazanjian,
president and chief executive  officer of Ultralife  Batteries.  "This quarter's
operating and gross margin expansion, and strong revenue growth, demonstrate the
positive  returns  we get from  additional  revenue  and the  management  team's
ability to execute on its near-term  growth plans. At the same time, we continue
to work  toward  expanding  in other  key  growth  markets,  including  medical,
automotive telematics and rechargeable."

Third Quarter and Full Year Outlook For the third quarter ending September 27, 2003, management expects operating income to exceed $2.1 million and revenue to reach at least $20.0 million. This compares to an operating loss of $1.9 in the same quarter the year before. In addition, management has revised its guidance for the full year 2003 and now estimates that operating income and revenue will be approximately $7.0 million and $75.0 million, respectively. This compares with an operating loss of $7.5 million, excluding a $14.3 million asset impairment charge, and revenue of $33.0 million, respectively, in 2002. The guidance management previously provided called for basic earnings per share in the range of $0.35 to $0.45 and revenues of $65.0 million, which assumed operating income in the range of approximately $5.0 million to $6.3 million.
