                                                                    Exhibit 99.1



          Ultralife Batteries Reports Fourth Quarter Results


    NEWARK, N.Y.--(BUSINESS WIRE)--Feb. 9, 2006--Ultralife Batteries,
Inc. (NASDAQ: ULBI) reported results for the fourth quarter and full
year periods ended December 31, 2005. Operating income for the quarter
was $0.1 million on revenues of $17.8 million. In comparison, the
company reported an operating loss of $3.4 million on revenue of $18.4
million for the same period last year. The operating loss in the prior
year included a non-cash impairment charge of $1.8 million related to
polymer rechargeable production equipment.
    The fourth quarter revenue reflects an increase in sales of
high-rate battery products offset by lower shipments of BA-5390
batteries to the U.S. military, as anticipated. Revenues associated
with technology contracts declined $0.8 million due to the timing of
development activity with various contracts. As a percentage of
revenues, gross margins were 21% compared to 11% in the same quarter
last year, mainly as a result of improved manufacturing efficiencies
in the U.K operation. Operating expenses were $3.5 million compared
with $3.7 million last year, excluding the $1.8 million impairment
charge last year. Income taxes in the fourth quarter of 2005 amounted
to a benefit of $0.2 million. The net loss for the fourth quarter of
2005 was $40,000, or less than $.01 per share, compared with net
income of $18.1 million, or $1.20 per diluted share, for the same
period a year ago. The results in the fourth quarter of 2004 reflected
a $21.1 million, or $1.41 per diluted share, income tax benefit
related to the recognition of a deferred tax asset associated with the
company's U.S. net operating loss carryforwards.
    For the twelve-month period ended December 31, 2005, revenues
totaled $70.5 million compared with $98.2 million reported for 2004. A
decline in shipments of BA-5390 batteries to the U.S. military was
partially offset by higher commercial revenues and other
military-related sales. The company reported an operating loss of $2.9
million for full year of 2005 compared to operating income of $5.1
million last year, reflecting lower gross margins associated with
lower volumes. The net loss for 2005 was $4.3 million, or $.30 per
share, compared to net income of $22.3 million, or $1.48 per diluted
share, for 2004, including the $21.1 million impact from the
recognition of the income tax benefit.
    "During 2005, Ultralife made great strides in building its
non-9-volt commercial business with revenues increasing by
approximately 40% on the strength of groundbreaking automotive
telematics contracts in addition to design wins in other target
markets where our power solutions add value to device applications,
notably search and rescue. We also succeeded in trimming our cost
structure in the second half of the year, as planned, realigning our
business model to be breakeven at the operating earnings line on $18
million in quarterly revenue," said John D. Kavazanjian, president and
chief executive officer.
    "Looking ahead, we are optimistic about the prospects for
continued growth of our commercial business. Our goals include adding
new automotive telematics contracts and continuing to convert design
wins into production contracts. As previously announced, adding Able
New Energy Co. Ltd. to the Ultralife family will also open up
significant new avenues for our commercial business while creating
opportunities to reduce costs even further by employing sourcing
alternatives in China," concluded Kavazanjian. "On the military side,
indications are favorable for renewed order flow from the U.S.
Military and we are ready to deliver with the qualified BA-5390A and
BA-5347 batteries. Over the course of 2006, we plan to complete the
qualification of the other batteries under the Next Gen II, Phase IV
award both in the U.S. and the U.K. while actively promoting the
migration from our competitors' sulfur dioxide chemistry to
Ultralife's manganese dioxide batteries. In summary, we are in an
excellent position competitively with an expanding set of target
market opportunities supported by an increasing array of power
solutions and improving operational efficiency."

    Outlook

    Management expects revenues in the first quarter of 2006 to be
approximately $21 million, including the restart of shipments of
BA-5390 batteries to the U.S. military. Management projects operating
income will be in the range of $750,000 in the first quarter,
excluding any impact from the expensing of stock options pursuant to
the adoption of FAS 123R. The company projects its first quarter
non-cash expense related to stock options will be approximately
$250,000.
    For the full year, the company anticipates quarterly growth
resulting in revenue of at least $90 million. Growth above $90 million
will depend on a number of factors, including the pace at which the
military transitions to manganese dioxide technology, and further
expansion in commercial markets.
