Japanese electronics makers Sharp and Fujitsu announced plans Friday to recall laptop batteries made by Sony, adding to an already massive global recall of the batteries that are at risk of overheating and catching fire.

Sharp Corp. said it was recalling 28,000 Sony-made battery packs for seven laptop models plus separately sold batteries, all for domestic Japanese use, according to company spokesman Hiroshi Takenami.

He said the company so far has received no reports of accidents such as those in the United States.

Another electronics maker, Fujitsu, said it would replace 51,000 more laptop batteries made by Sony Corp., following a similar move earlier this month covering 287,000 Sony-made laptop batteries worldwide.
