Panasonic Corp will recall 43,140 battery packs used in notebook computers after three incidents of the batteries overheating and catching fire, the company said on Wednesday. Panasonic has been restructuring its business to shift its focus from volatile consumer markets to more reliably profitable industrial products, such as car batteries. It is the prime supplier of lithium batteries to electric automaker Tesla Motors Inc, and said last week that it expects to become the sole manufacturer in Teslas planned multibillion-dollar U.S. battery factory. Tesla uses a similar type of cell used by notebook computers, but a Panasonic representative said the batteries involved in the recall were different from those that it supplies to Tesla and so there was no impact on the automaker.
