Fujitsu has become the latest notebook computer manufacturer to ask its customers to send back batteries made by Sony. Acer may be about to do the same.

Fujitsu today said it was recalling 287,000 Sony-made notebook batteries, Reuters reports. That's in addition to the 4.2m being recalled by Dell, 1.8m by Apple, 830,000 by Toshiba and 526,000 by Lenovo. Fujitsu's recall brings the total to over 7.6m units.

That will grow further if Acer announces a recall too. Earlier this week it emerged the company was in talks with Sony about the issue. Now, that's not a guarantee Acer will ask its customers to send batteries back, but Fujitsu likewise was initially reported to be discussing the problem with Sony and has now formally announced a recall.

It's not clear whether Fujitsu has received reports that any of its laptops overheated and caught fire as a number of other brands' machines have. Acer spokespeople were last week quoted as claiming the company has received no such complaints from its customers. ®
