      Ultralife Batteries Reports Second Quarter Revenues of $21.4 Million;
                  Management Increases Fiscal 2006 Guidance to
        Reflect the Acquisitions of ABLE New Energy and McDowell Research


    NEWARK, N.Y.--(BUSINESS WIRE)--Aug. 3, 2006--Ultralife Batteries,
Inc. (NASDAQ: ULBI) reported results for the second quarter ended July
1, 2006. Operating income for the quarter was $0.5 million on revenues
of $21.4 million. Included in operating income was stock-based
compensation expense of $0.3 million. In comparison, the company
reported operating income of $0.2 million on revenues of $21.6 million
for the same period last year.
    Second quarter revenues reflect growth from the company's
automotive telematics products partially offset by lower BA-5390
battery shipments. As a percentage of revenues, gross margins amounted
to 20% compared with 19% in the same quarter last year. Operating
expenses were $3.9 million, including $0.3 million in stock-based
compensation expense, compared to $4.0 million in operating expenses a
year ago. Net income for the second quarter of 2006 was $0.1 million,
or $0.01 per diluted common share, compared to a net loss of $1.4
million, or $0.10 loss per diluted common share, for the second
quarter of 2005.
    For the six-month period ended July 1, 2006, revenues totaled
$39.7 million compared to $37.0 million for the same period last year.
The company reported operating income of $0.7 million, including $0.6
million in stock-based compensation expense, compared to an operating
loss of $1.5 million for the first six months of 2005. Net income for
the first half of 2006 was $0.3 million, or $0.02 per share, compared
to a net loss for the same period last year of $3.0 million, or $0.21
per share.
    "Having met our financial and strategic goals for the second
quarter of 2006, we are focusing our efforts on accomplishing our
plans for the year, which include continuing to grow our commercial
business and diversify our government/military business, and
integrating the two companies we recently acquired, ABLE New Energy
and McDowell Research," said John D. Kavazanjian, president and chief
executive officer. "We are making progress in strengthening our
presence in target commercial markets, notably automotive telematics,
where this quarter we expanded a customer relationship to supply
another platform for model year 2007.
    "The addition of ABLE advances Ultralife's position as the
supplier of choice of high-energy power sources to commercial
customers in an expanding set of target markets. We have already
started selling ABLE's products and are enhancing their operations by
leveraging our engineering and manufacturing process expertise,"
continued Mr. Kavazanjian. "McDowell builds on our efforts to
diversify our government/military business by extending our
penetration into foreign defense organizations and the growing special
operations area while strengthening our relationships with U.S. prime
defense contractors. We are coordinating our strategies to operate as
an integrated company with a diversified set of growth opportunities
supported by broadened sales coverage and an expanded product
portfolio."
    Mr. Kavazanjian concluded, "The traction we are gaining in the
commercial business, coupled with the opportunities we have to broaden
our government/military business, supports our confidence in our
second half outlook."

    Outlook

    Management has revised its guidance for the full year 2006 to
include the contributions from ABLE and McDowell. For the full year of
2006, the company now expects revenues of approximately $100 million.
For the third quarter of 2006 management expects revenues to be
between $25 million and $29 million and operating income to be in the
range of $1.2 million to $2.4 million, including approximately $0.4
million in non-cash stock-based compensation expense.
