25 - 45 minutes
I had to replace the iPod Mini Battery
It was good. One of the screws accidentally got stripped so I needed a few more screwdrivers to get the screw out.
The battery is slightly bigger than the original so putting it back together is a bit difficult and a tight fit. It doesn't have the same cut out as the original so it will be hard shoving everything back in the case. Be careful not to pinch the wires from the battery.
Gentle on the screws! They can be stripped easily!
