Late 2008 aluminum macbook. My wife is primary user. Told me last few weeks the trackpad responds erratically. More recently the battery cover seems to be bulging. Finlly removed the battery and found essentially identical to the original poster's exploding (slowly) battery problem.So this must be well known to Apple by now
Works well on AC power now but battery cover clips have been in part dislodged from cover itself, so holding it down with duct tape.
Have an appointment with Apple Store set up by Apple Care but questions:
1.I can't find that a replacement battery exists--anyone know?
2. Can Apple actually repair or replace the battery cover?
3. If not repairable what options?
