Rechargeable power bank for cellphone etc has swollen up and broke open the plastic case. It's expanded so that I can't press the sides of the shell together. There's no leakage. It was in a fabric pouch, so easy to tell. No warmth or heat.
Pressing the test button lights up the charge indicator lights. Seems to be fully charged.
I've had it for maybe five years. Used only a couple of times. Kept charged. Last checked within the last two months.
Any idea what happened? Is it dangerous, getting ready to explode?
