[sudo-discuss] gopro hero or hero2 battery?

Daniel gave someone 2 broken gopros (hero2 & 3) who gave them to liberated lens. Daniel & i finally got around to trying to fix one (hero3), yesterday, & we succeeded by reseating a ribbon cable on the motherboard & cleaning the shutter's electrical contact, also, on the motherboard. does anyone has an original gopro hero or gopro hero2 battery that i could borrow to see if the other one can be fixed? i don't mind buying a battery but i'd rather not unless i know the thing can be fixed. thx
