Tl;Dr

As the battery rests in a deep discharge state, the electrolyte breaks down, turns into gas, and the battery poofs up.

I found this with my old PSP that I had stored away for years and pulled out one day for nostalgia purposes. Popped the battery cover off and it was all swollen like a balloon. It was quite a terrifying issue to have to deal with. Back in the old land of reddit, they even had a sub dedicated to this called r/spicypillows
