On Tuesday, Matsushita Electric Industrial said it had started recalling 6,000 PC batteries as they could overheat when subjected to a strong impact.
The spokesman said there had been no cases of the batteries in question catching fire and no one had been injured, and it was unclear how much the recall would cost the company.
The Matsushita spokesman said that when a notebook PC using the battery in question had been accidentally dropped on the floor or suffered any other strong impact, there was a chance that a tiny metal spring used in the battery pack could fall off on to battery cells, causing overheating.
The batteries were loaded in some of Matsushita's notebook PCs made in April and May 2005 and sold in Japan. The batteries were not manufactured by Panasonic or Sony.
