Apple has recalled nearly 2 million iBook and Powerbook batteries, these are Sony-sourced battery units much like the ones recalled recently by Dell. Dell’s recall affected over 4 million units. That is a lot of Sony batteries, and I understand that Sony is covering a large chunk of the replacement costs of both recalls.

It would behoove you to make sure you are not affected by the recall by visiting the above listed site to check your serial number(s). I believe that Dell has also recently expanded the range of serial numbers requiring replacement in it’s recall, so if you’ve already checked once you might want to check again.

The latest Apple recall does not affect Macbook or Macbook Pro models, though there was a recall earlier this year on a small number of early 15″ Macbook Pro batts, apparently due to performance (and not the potential of asploding and rendering you sterile).
