INDEX TO EXHIBITS (99) Additional Exhibits 99.1 Press Release dated February 15, 2007.

                                                                    Exhibit 99.1

          Ultralife Batteries Reports Fourth Quarter Results


    NEWARK, N.Y.--(BUSINESS WIRE)--Feb. 15, 2007--Ultralife Batteries,
Inc. (NASDAQ: ULBI) reported an operating loss of $1.5 million on
record quarterly revenues of $30.1 million for the fourth quarter
ended December 31, 2006. In comparison, the company reported an
operating profit of $0.1 million on revenues of $17.8 million for the
same period last year.

    Revenues in the fourth quarter of 2006 reflect growth in sales of
rechargeable batteries and chargers, 9-volt batteries and automotive
telematics products as well as the addition of McDowell Research and
ABLE New Energy, which were acquired in 2006. As a percentage of
revenues, gross margins for the fourth quarter of 2006 were 17%
compared to 21% for the same period last year, due to higher than
expected material costs at McDowell and certain manufacturing
inefficiencies in 9-volt production. Operating expenses totaled $6.6
million and included $1.7 million of additional expenses from McDowell
and ABLE, $0.7 million of intangible asset amortization and $0.5
million of stock-based compensation expense; excluding these items,
operating expenses rose modestly over the $3.5 million reported in the
fourth quarter last year.

    At the end of 2004, the company recorded a deferred tax asset
associated with its U.S. net operating loss carryforwards as the
company had begun to demonstrate a profitable track record. The
company continually assesses the carrying value of this asset based on
relevant accounting standards. The company's assessment in the fourth
quarter of 2006 concluded by reestablishing full reserves against this
deferred tax asset, generating a $24.1 million non-cash charge to
income taxes. As the company reestablishes a pattern of profitability,
it will continue to reassess the reserves associated with this issue.
As a result of the above, net loss for the fourth quarter of 2006 was
$26.0 million, or $1.73 per common share, compared to a net loss of
$40,000, or $0.00 per common share, for the fourth quarter of 2005.

    For the full year ended December 31, 2006, revenues totaled $93.5
million, a 33% increase over the $70.5 million reported for 2005. The
company reported an operating loss of $3.0 million in 2006, including
$1.5 million in stock-based compensation expense and $1.2 million of
intangible amortization, compared to an operating loss of $2.9 million
in 2005. Net loss for 2006 was $27.5 million, or $1.84 per share,
including the adjustment for the deferred tax asset, compared to a net
loss for the same period last year of $4.3 million, or $0.30 per
share.

    Management cautions that the fourth quarter and full year results
are subject to the completion of its year-end audit by the company's
independent accounting firm. In particular, the final review related
to McDowell's inventory valuation and associated cost of goods sold
has not yet been completed. As a result, final financial statements
reported in the Form 10-K for the year ended December 31, 2006 may
differ from the results reported in this press release.

    "During 2006, we accomplished a great deal while facing numerous
challenges," said John D. Kavazanjian, Ultralife's president and chief
executive officer. "Diversifying our market opportunities and reducing
our dependence on orders from the U.S. Defense Department were
strategic priorities for the company and we achieved these objectives
by further building our commercial business, particularly in the area
of automotive telematics, and by expanding our reach into different
segments of the government/military market. As evidence of our success
in diversifying revenues, sales of standard batteries under contract
with the U.S. Defense Department for all of 2006 were approximately
$18 million, or 19% of total revenue, and only $1.0 million in the
fourth quarter, or 3% of total revenue. As a result of our key
initiatives to solidify our business with military prime contractors,
nurture relationships with automotive manufacturers and strengthen our
global distribution network, we now possess a broader set of market
opportunities and see greater demand for our power solutions than ever
before.

    "The challenges we faced in 2006 were principally related to the
integration of McDowell Research and associated operational issues
that arose in the second half of the year," continued Mr. Kavazanjian.
"As stated in our fourth quarter pre-announcement, we are addressing
the operational issues and are resolved to improve manufacturing
efficiency and optimize McDowell's cost structure. The actions we took
in early January to address manufacturing issues at our Newark
facility are proving to be effective and we are now operating at
planned levels. In addition, we are working through McDowell's
inventory that carries above-normal product costs and have made the
necessary changes to lower future costs."

    Concluded Mr. Kavazanjian, "Ultralife's mix of business today is
very different than a year ago, combining a steady revenue base in our
established commercial market segments and expanding activity with
military prime contractors who value our engineering expertise and
broad product offering, supplemented by design wins in target
commercial markets and by U.S. military orders against existing
contracts."

    Outlook

    Management is projecting revenue between $28 million to $30
million for its first quarter ending March 31, 2007, largely based on
our current backlog of shipments in addition to our pipeline of
orders. Based on this revenue estimate, management anticipates
reporting an operating loss in the range of $1 million up to
breakeven, inclusive of approximately $1.1 million of non-cash
expenses related to stock-based compensation and intangible asset
amortization.
