My 3rd Gen ipod is just over 2 years old now. I’ve abused the poor battery a lot, and now it has a life of about 1 hour. I went on http://www.trademe.co.nz and found a replacement battery kit for a 850mAh battery (apparently 30% more capacity than OEM battery). the kit comes with a battery, instructions, and 2 nylon tools for prying the thing open (so you don’t scratch the case). I’m going to replace the battery tonight I think – of course that depends if I go out for drinks after work. I’ll be documenting the replacement on my blog I think. I’ll keep you all posted.
