@alexbuzzbee My old MBP solved that problem by the battery swelling so much that it broke off the flanges connecting the battery to the case!
Also though, I found that leaving it plugged in made the swelling go down and it hasn't swollen up since. YMMV, of course, I understand if you'd rather play it safe...
@jamesnvc I also found something saying that freezing a Li-ion can revive it, but I don't want to do anything at all that could help it decide to catch fire. The plan is to remove the battery and swap the SSD into another identical MacBook Pro (hoping the SSD isn't soldered and assuming it won't power on without the battery).
