i recently bought a used 2 month old 3rd generation 15gb ipod with firmware version 2.1 from a reputable person off ebay...it is currently formatted for mac and I use pc..so i haven't even used it myself yet but i noticed that when I plugged it in to charge it...it indicated the unit was charging on the lcd screen and everything seemed honky dory. When I came back at a later time to see the screen indicating that it was "charged" and no longer flashing/moving as the manual describes...i unplugged it and to my surprise the battery indicator said it was only half charged? I thought "what the hell?" i recalled reading that if it wasn't used in a while it would do weird things so i plugged it back in...again it said the unit was charging and then when i unplugged it later after it said it was charged...the battery indicator said 3/4 full? I did it 2 more times before it indicated a full charge! Is this normal?

In addition...i haven't used it since but I have noticed that the battery level has dropped...which i understand it normal without use, but...I've noticed that the bloody indicator will start at a certain level once I turn it on...and then increase? Anyone have any insight? Thanks a lot in advance.
