In my life, I've used alot of different iPods (somehow my iPods always tend to die under different circumstances, be it my dog or nephews :) And of course, while iPod is a great music device in general, it's battery is kind of a weak side, so I had to experiment with different original and 3rd party ones. This website represents a sacred collection of my knowledge on ipod batteries, so, enjoy and, hopefully, benefit from it:)
