          Ultralife Batteries Reports Second Quarter Results

                Revenues Increase 65% to $35.2 Million


    NEWARK, N.Y.--(BUSINESS WIRE)--Aug. 2, 2007--Ultralife Batteries,
Inc. (NASDAQ: ULBI) reported record revenues of $35.2 million for its
second quarter of 2007, an increase of 65% compared with $21.4 million
reported in the same three-month period in 2006. Operating income rose
more than three-fold to $1.7 million compared with $0.5 million a year
ago.

    Second quarter revenues grew $13.8 million year-over-year due in
part to higher sales to international governments and defense
organizations, as well as the addition of communications accessories
sales from the McDowell acquisition which the company completed in
mid-2006. As a percentage of revenues, gross margin for the second
quarter of 2007 was 24%, up from 20% a year ago due to higher sales
and production volumes and a shift toward more highly engineered
products. Operating expenses totaled $6.9 million, which included $1.4
million of additional expenses and $0.6 million of intangible asset
amortization connected with last year's acquisitions. Excluding these
items, operating expenses rose $1.0 million over the $3.9 million
reported in the comparable quarter last year due to increased
corporate costs required to operate a larger, more diverse business.
Net interest expense was $0.6 million in the second quarter of 2007,
up from $0.2 million reported in the prior year due to the increased
debt to finance last year's acquisitions. Net income for the second
quarter of 2007 was $1.3 million, or $0.08 per diluted share, compared
with net income of $109,000, or $0.01 per share, for the same quarter
in 2006.

    For the six-month period ended June 30, 2007, revenues totaled
$67.5 million compared to $39.7 million for the same period a year
ago. Operating income amounted to $2.3 million for the first half of
2007, an increase of $1.6 million over 2006. Net income for the first
half of 2007 was $1.3 million, or $0.08 per diluted share, compared to
$249,000, or $0.02 per share, for the same period last year.

    "Second quarter results offer solid evidence of the success we
have achieved in diversifying the company's government/defense revenue
mix and in broadening the range of our product offering, coupled with
our commitment to improving operational efficiencies," said John D.
Kavazanjian, Ultralife's president and chief executive officer.
"Second quarter revenue marked the fourth consecutive quarter of
year-over-year growth and surpassed last quarter's record level. In
addition, we continued to drive gross margin expansion as we increased
the contribution of higher engineered products and improved
manufacturing efficiencies. Asset utilization also improved with
inventory levels and revolver borrowings down from the first quarter."

    "To build on these positive trends in margins and asset
utilization, we are continuing to push for margin improvement in our
communications accessories business and for even better operational
efficiencies across the organization," continued Kavazanjian. "At the
same time, we are addressing an ever-widening set of growth
opportunities as demand for portable power in new and existing
applications is proliferating in both government/defense and
commercial markets. With an expanding portfolio of high performance
products, supported by our unrivaled product development capability
and engineering expertise, and an established global distribution
network, we are in an excellent position to translate these
opportunities into continued profitable revenue growth."

    Outlook

    Management is projecting revenue between $33 million and $36
million for its third quarter ending September 29, 2007, based on
current backlog, anticipated orders and anticipated delivery
schedules. Based on this revenue estimate, management anticipates
reporting operating income in the range of $1.2 million to $1.8
million, inclusive of approximately $1.0 million of non-cash expenses
related to stock-based compensation and intangible asset amortization.
