WASHINGTON (Reuters) - Ultralife Corp (ULBI.O) makes the lithium-manganese battery that powers the emergency transmitter that is being investigated as a possible cause of last week's fire on a Boeing 787 in London, a source familiar with the investigation said on Monday.
As reported earlier, the emergency locator transmitter, or ELT, is made by Honeywell International Inc (HON.N).
Ultralife, based in Newark, New York, was not immediately available for comment.
Honeywell says it has produced over 3,000 of the emergency beacons, equipped with the lithium-manganese batteries, since 2005, and there have been no safety incidents.
