Do you have an online source backing this up? Because people report Apple does't care, at least in some cases:
> Apple support have refused to provide any assistance, simply stating that the MacBookAir is out of warranty. They just said this behaviour (rapid expansion of a battery) "can be expected" in some cases.
If it's an expanded battery and you are out of warranty, they should only charge the cost of the battery to get that fixed up, so you wouldn't be out of pocket for the top case part (which is much more expensive) nor any other components that may have been damaged by the expansion.
