Hey, all of you guys with "exploding", "expanding", "swelling", whatever batteries. If you haven't called Apple yet, do so. What is the worse that they can tell you? That it isn't covered? Well, if that's their answer, you are no worse off, you are only out a few minutes of time and there is a case created in their system (unlike complaining here) that you are having this problem.
But who knows, if you are nice and aren't screaming and hollering, they just might be able to so something. Then again, they might charge you for the battery replacement, $80 if I remember correctly, but they might cover the parts damaged by the battery.
Who knows for sure what they will do, but IMHO its worth a shot.
