First Dell pulls back 4.1 million laptop batteries, and now Apple is recalling 1.8 million laptop batteries too. And like Dell's, the affected Apple batteries were made by Sony. (Does Sony not use its own batteries in its own laptops?)

Affected models are the 12-inch iBook G4, the 12-inch PowerBook G4, and the 15-inch PowerBook G4. If you think you have a recalled battery in your laptop, first, stop using it. And then visit Apple's recall site or call the company at (800) 275-2273 to request a replacement battery. Apple said there were "no major injuries" resulting from the recalled batteries, but better safe than sorry.

What a sad fiasco for both companies.

Which other companies use Sony batteries? Just a couple small ones, like Lenovo and HP. Interestingly, these same companies are going to get together in San Jose in a few weeks to talk about a battery manufacturing standards. A good idea, if a little late.
