New and Old Battery Not Charging
My ipod video battery life was down to 20-30 minutes, so I bought a replacement battery. After installing the new battery and charging for 8 hours or so, I turned on the ipod and it worked fine. Then I unplugged the ipod from the charger and it immediately lost power. It didn't hold any charge.
I then put the old battery back in, figuring the problem was with the new battery, but now the same thing is happening. The old battery that used to last 20-30 minutes on a full charge now works fine when plugged into a charger but then immediately loses power when unplugged.
Any thoughts on why this is?
My first guess here would be a bad battery. But I do know that the iPods do have issues with the charging circuitry. You could try to use a multimeter at the connector for the battery to see if you have any voltage. That might give you the answer you need to determine what to do next. Give it a try and let us know how it went. Good luck
