INDEX TO EXHIBITS (99) Additional Exhibits 99.1 Press Release dated February 10, 2005.

                                                                    EXHIBIT 99.1

       Ultralife Batteries, Inc. Reports Fourth Quarter Results

    NEWARK, N.Y.--(BUSINESS WIRE)--Feb. 10, 2005--Ultralife Batteries,
Inc. (NASDAQ:ULBI) today reported results for the fourth quarter and
full year periods ended December 31, 2004. Revenues for the quarter
were $18.4 million compared to $24.0 million for the prior year
quarter. As a percentage of revenues, gross margins were 11% compared
to 22% in the same quarter last year due mainly to reduced production
volumes.
    During the fourth quarter of 2004, the company recorded a non-cash
impairment charge of $1.8 million related to polymer rechargeable
production equipment, owned and leased, that it no longer expects to
utilize. Excluding this charge, operating expenses were $3.7 million,
a $0.7 million increase over last year's fourth quarter, attributable
to a greater focus on the development of new products and additional
selling, general and administrative resources needed to support the
company's growth objectives. Operating loss for the quarter, which
includes the $1.8 million impairment charge, was $3.4 million versus
operating income of $2.3 million for the same period last year.
    Given its move to profitability over the past two years, the
company recorded a deferred tax asset at the end of 2004 associated
with its U.S. net operating loss carryforwards due to the belief that
the company has a reasonable probability of utilizing these benefits
to offset future taxable income. As a result, the company recorded an
income tax benefit during the fourth quarter of $21.1 million, which
had a nominal impact on cash flows.
    Net income for the fourth quarter of 2004 was $18.1 million, or
$1.20 per diluted share. This compares with net income of $2.2
million, or $0.15 per diluted share, in the similar quarter in 2003.
    For the full year ended December 31, 2004, revenues reached $98.2
million, a 24% increase over the $79.5 million reported in 2003. The
year-over-year improvement was driven by an increase in military
sales, primarily higher shipments of BA-5390s, as well as a five-fold
increase in rechargeable revenues that reached $8.1 million. Operating
income for 2004 amounted to $5.1 million, including the $1.8 million
impairment charge taken in the fourth quarter. Net income for the
twelve-month period of 2004 was $22.3 million, or $1.48 per diluted
share, and included a $4.0 million second quarter non-cash charge
related to the company's investment in Ultralife Taiwan, Inc., as well
as a $21.1 million income tax benefit related to the recognition of a
deferred tax asset. In 2003, the company reported operating income of
$6.0 million and net income of $6.4 million, or $0.46 per diluted
share.
    "Fourth quarter results were close to our expectations. We are
particularly pleased with the progress of our rechargeable business
which performed especially well, breaking even on a gross margin basis
in the quarter and for the year producing revenue in excess of our $7
million goal," said John Kavazanjian, president and chief executive
officer.
    "Demand from the military for high-performance batteries in the
field and for training remains quite high, particularly for our
BA-5390 batteries, and we remain confident that this will continue to
be a strong business for Ultralife in 2005," Kavazanjian added. "In
addition, 2005 is shaping up to be the year in which we gain
meaningful traction in a number of our target commercial markets as
design application opportunities move into volume production and as we
advance the development work underway by our engineered services
group. Our unique offering in automotive telematics in particular
looks very promising especially given the rate of adoption of
telematics as an automotive safety system. We are also accelerating
our pace of new product development, stepping up our efforts to
capitalize on opportunities for engineered solutions, and continuing
to broaden our product offering with an emphasis on charging systems
and accessories. All of these growth initiatives further capitalize on
Ultralife's leading energy technology, unique breadth of power
solutions and process-engineering expertise, and keep us on track to
achieve our goal of becoming a $200 million revenue company in the
next few years."

    Outlook

    For the first quarter ending April 2, 2005, management currently
projects revenues of at least $18.0 million and an operating loss of
approximately $0.8 million, assuming that the company is awarded an
urgent buy order for BA-5390 batteries with the U.S. military.
    For the full year of 2005, management continues to expect revenue
growth of 10% to 20% over 2004. This growth is expected to result from
continued success in growing commercial business, in key target
markets such as medical and automotive telematics. This revenue growth
target also assumes sizeable order activity from the U.S. military, in
conjunction with the award of the Next Gen II Phase IV contract (as
well as a favorable resolution of the recent protest of that contract
in a timely fashion) and other anticipated contract activity. Order
activity and shipments are expected to increase throughout the year,
as commercial orders take hold and the military business stabilizes.
Operating income in 2005 is expected to show steady growth throughout
the year, returning to profitability in the second quarter and moving
toward the company's near-term operating margin target of 15% by
year-end. Management's operating income guidance excludes any
potential impact from expensing stock options, which if the current
accounting standards remain unchanged, the company would be required
to recognize beginning no later than the third quarter of 2005.
Management expects that its overall effective income tax rate will be
in the range of 40% of pre-tax earnings during 2005, although actual
cash payments for income taxes are expected to be nominal as the
company utilizes its net operating loss carryforwards to offset
taxable income.
