I got a refurbished iPod from Powermax in July, and it was great, had no scratches and so on, and I had a battery life of around 8 hours even with the latest update 1.2.2 (Europe update). Now, the battery is all messed up. I had it plugged to my Mac for HOURS and unplugged it. Then after few seconds of turning on, the message appeared "battery empty"... WTF?? What could I do? HELP!!!
