Exhibit 99.1

                Ultralife Batteries Reports Third Quarter Results


    NEWARK, N.Y.--(BUSINESS WIRE)--Nov. 3, 2005--Ultralife Batteries,
Inc. (NASDAQ: ULBI) reported results for the third quarter ended
October 1, 2005. Revenues for the quarter were $15.7 million compared
to $24.4 million for the same period last year. Operating loss for the
quarter was $1.5 million compared with operating income of $1.5
million for the same period last year.
    The third quarter revenue reflects lower shipments of BA-5390
batteries to the U.S. military, as anticipated. Gross margins for the
quarter were 15% compared to 20% in the same quarter last year,
reflecting lower production volumes. Operating expenses were $3.9
million compared with $3.3 million last year, reflecting an increased
commitment to new product development and higher administrative costs.
Income taxes in the third quarter of 2005 amounted to a benefit of
$0.4 million. The net loss for the third quarter of 2005 was $1.3
million, or $0.09 per share, compared with net income of $1.4 million,
or $0.09 per diluted share, for the same period a year ago.
    For the nine-month period ended October 1, 2005, revenues totaled
$52.7 million compared with $79.8 million reported for the same period
last year, resulting mainly from lower shipments of BA-5390 batteries
to the U.S. military, and offset in part by higher commercial revenues
and other military-related sales. The company reported an operating
loss of $3.0 million for the first nine months of 2005 compared to
operating income of $8.5 million last year, reflecting the revenue
decline and higher operating expenses. The net loss for the first nine
months of 2005 was $4.3 million, or $0.30 per share, compared to net
income of $4.3 million, or $0.28 per diluted share, for 2004.
    "Ultralife's third quarter results were essentially consistent
with our latest guidance, which assumed no order activity from the
U.S. military for BA-5390 batteries," said John D. Kavazanjian,
president and chief executive officer. "As anticipated, we did finish
all testing on the new version of the BA-5390 with the state-of-charge
indicator in September and the qualification process is in the final
approval stage. Longer term, the U.S. military has issued new
guidelines requiring a state-of-charge indicator in all new contracts
for multi-cell batteries, a development which bolsters our conviction
that our competitive advantages create a strong opportunity for us to
continue gaining share in the military market.
    "In addition, during the third quarter we continued to advance our
commercial business as we started shipping to new search and rescue
customers, maintained strong activity in medical applications, and
began production under our new automotive telematics backup battery
contract for shipments starting in the fourth quarter."
    Kavazanjian concluded, "Recognizing the ongoing uncertain timing
and quantity of BA-5390 orders, we took steps in the third quarter to
reduce overhead costs by up to $1 million on a quarterly basis. We
expect these actions, including the implementation of tightened
spending controls and greater expense scrutiny, will reduce our
breakeven cost infrastructure to $18 million in quarterly revenues,
assuming a steady rate of production. With this cost structure, we
still have the manufacturing flexibility necessary to ramp up quickly
in response to a resumption in BA-5390 orders."

    Outlook

    Management expects fourth quarter revenues to be in the range of
$19 million, consistent with the most recent guidance for the
company's second half revenues of approximately $35 million, assuming
no BA-5390 order activity from the U.S. military. Sales to commercial
customers, particularly in the automotive telematics market, are
expected to grow from the third quarter, as are sales of other battery
products direct to the military and military battery assemblers. In an
effort to further trim current inventory levels, production rates are
projected to remain temporarily lower throughout the fourth quarter.
This will likely result in under-absorbed manufacturing overheads and,
as a result, management is projecting an operating loss in the range
of $0.5 million for the fourth quarter.
