(NASDAQ: ULBI) has received a contract valued at approximately $7 million to supply BA-5590 lithium-sulfur dioxide batteries to the U.K. Ministry of Defence. Ultralife will provide the MoD with batteries manufactured by EaglePicher Technologies, LLC through a supply agreement. Deliveries are expected to begin this quarter and be completed in the fourth quarter. "This very significant contract offers clear evidence of the depth of Ultralife's international selling capabilities," said John D. Kavazanjian, Ultralife's president and chief executive officer. "While we already supply our industry-leading lithium-manganese dioxide BA-5390 batteries to the MoD, we recognize that our customers sometimes require alternatives.
