Well that was fun. Not! Bloated battery. Got it out by force (blunt tool to the back of the battery and a hammer to push it out)! Givning birth is easier!! Well… one of the cables to the USB charger was probably disconnected, even if I tried to reset them. Now I have a dead JBL Flip 4 and I’m !#^&@@. Maybe once the steam has worn off, I’ll try to figure out how to find any tools to see if I can get the USB charger hooked up. But then again, it might just be a wasted amount of money for a new battery and now a new Flip 4. Anyway, it’s dead as a door nail.
