How to change your iPod touch and iPhone battery
Batteries for the iPod touch, iPhone, and much more can be purchased from http://www.milliamp.com
Using a thin, but sturdy guitar pick, carefully separate the backing of the iPod from the screen. This may be tough to do because the chrome backing snaps to the touch screen assembly, and care must be taken to prevent cracking the screen.
Once the chrome backing is separated from the iPod, the battery is now exposed.
If the battery has never been changed, it will more than likely be glued in place, and must be carefully removed with the guitar pick as well.
The wires must be soldered and taped with electrical tape, or carefully protected with heat shrink tubing. There is not much clearance available inside the iPod, so keep this in mind when finishing up with the wiring and protecting the wires from shorting.
Carefully put the new battery in the old batteries spot, and snap the chrome backing back together with the front screen.
Charge the iPod for at least 10 minutes before attempting to turn it on, but keep it on the charger until it is fully charged for best results.
