...if I buy one online? My 160GB Pod is no longer under warranty and will not charge, even after being left plugged in for more than 5 hours. (And no, it's not the computer of the cord). It's about 2-3 years old. The Please Wait Low Battery screen is all that will ever show. So, replacing the battery, better online or through Apple? And any suggestions on a legit site to get a battery?
