I decided to set up my long dormant Pandora today, which meant charging the battery. Unfortunately, I suspected the battery was bad and was proven right as it swelled up and popped the cover loose during charging. The cover is still intact, but given that the store is sold out of batteries, is there another alternative? Is there a readily available hobbyist battery or something along those lines that can be modified to work with the Pandora? Has anyone done anything similar? Or is this thing doomed now?
