My gen3 Ipod has served me well on many a long plane trip across the world or within Australia but after several years the battery has lost it lifespan. I had simply assumed it would spend the rest of it life in its dock until I came across this do-it-yourself battery placement kit at Jaycar.
The instructions were clear, read step 1 before step 2 . I almost stuffed up but laying on it back it is actually quite easy to pop open an ipod. For AU$30 my ipod has new life and is ready for our trip to Thailand.
