I am not part of this site or get cash for this info, but I thought it would help, so I am sharing the info.
One of the few things we don't like about iPods is the battery you can't replace. After about 18 months, plan to send your iPod back to Apple wrapped in a $100 bill--that's about the time you'll need a new battery, because the old one will have crapped out.
If that rankles you like it does me, check out ipodbattery.com. Not only does it have replacement iPod batteries for every iPod made, the prices are nice and the photo tutorials on taking your iPod apart are absolutely exemplary. If assembling a piece of IKEA furniture takes you all day (and it still leans funny when you're done), then this project isn't for you. Otherwise, you'll save money and get the satisfaction of not being treated like a child.
