So i have a gopro hero 2 and it doesn't hold a charge, i will charge it and it will say it has a full battery but then i will wait a day until i need to use it and it is dead when i turn it on. it hasn't accidentally gotten turned on or anything. I use a regular charger that comes with the go pro but i did try to charge it on a wall with a usb charger once or twice. Any advise would be helpful. thanks
try to replace it through warrenty, if that fails then just pick up 1 or 2 replacement battery packs. There not very expensive, and if you have more then one, it takes the stress of of using the same pack all the time.
