The battery is attached to the rear panel with adhesive. Be careful not to tear the orange headphone jack or hold button ribbon cables when removing the battery.

Use a spudger to lift the battery and the attached orange cable out of the iPod. If you have a 160 GB iPod, the battery will be thicker than the one pictured.

If you have trouble removing the battery, you can use a hair dryer or a heat gun on the back of the iPod to soften the glue holding the battery in place. Be careful not to overheat the battery.
