          Ultralife Batteries Reports First Quarter Results

             Revenues Rise 76% Over Same Period Last Year


    NEWARK, N.Y.--(BUSINESS WIRE)--May 3, 2007--Ultralife Batteries,
Inc. (NASDAQ: ULBI) reported record quarterly revenues of $32.3
million, an increase of 76% over the $18.3 million reported in the
same three-month period in 2006. Operating income for the first
quarter of 2007 was $0.6 million compared with $0.2 million a year
ago.

    Revenues in the first quarter of 2007 rose $14.0 million over the
first quarter of 2006, primarily due to sales growth across most
product lines, in addition to the contribution of businesses acquired
last year. As a percentage of revenues, gross margins for the first
quarter of 2007 were 23%. Operating expenses totaled $6.9 million and
included $1.7 million of additional expenses related to last year's
acquisitions, and $0.5 million of intangible asset amortization.
Excluding these items, operating expenses rose $1.0 million over the
$3.7 million reported in the first 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 first quarter of 2007, up
from $0.2 million reported in the prior year due to higher outstanding
debt resulting from acquisition activity. Net loss for the first
quarter of 2007 was $36,000, or $0.00 per common share, compared to
net income of $140,000, or $0.01 per common share, for the same
quarter in 2006.

    "Ultralife executed well in the first quarter, delivering strong
year-over-year revenue growth across all areas of our business," said
John D. Kavazanjian, Ultralife's president and chief executive
officer. "As further evidence of our reduced dependence on the U.S.
Department of Defense, sales of standard military batteries under
contract accounted for 9% of total revenue. In addition, we are
succeeding in our efforts to aggressively drive sales of
communications accessories, with revenues reaching $8.5 million,
nearly double the level reported in the fourth quarter.

    "Operationally, we returned to planned efficiencies in our 9-volt
operations and utilized a significant portion of premium cost
inventory thanks to strong sales of communications accessories,"
Kavazanjian continued. "Although these actions improved our cost
structure somewhat, we have more work ahead to lower our cost base. We
are continuing to identify areas where we can boost productivity,
increase gross margins through cost-effective sourcing of materials
for manufacturing communications accessories, and further leverage
engineering and sales resources."

    Kavazanjian concluded, "The first quarter's solid sales reinforce
our conviction that the prospects for growth have never been better.
We intend to continue to capitalize on the many opportunities in the
government/defense and commercial markets, leveraging our broad
product portfolio, global distribution network and growing reputation
for engineering skill among prime contractors. Through these efforts,
coupled with our operational improvements, we are optimistic that we
will post top- and bottom-line growth in 2007."

    Outlook

    Management is projecting revenue between $32 million and $34
million for its second quarter ending June 30, 2007, largely based on
a strong backlog of orders and the company's anticipated delivery
schedules. Based on this revenue estimate, management anticipates
reporting operating income in the range of $0.8 million to $1.2
million, inclusive of approximately $1.1 million of non-cash expenses
related to stock-based compensation and intangible asset amortization.
