a few months ago i bought a second generation ipod (20 gig) used from a friend for $100. when i say second generation, i mean this one. anyway, the battery has been going downhill, it can barely hold ...

I've got a 3rd gen 40GB ipod which is not covered by Apple's manufacturer warranty anymore as it is over a year old & I didn't buy extended warranty. The battery barely manages to last over 2-3 hours.
