[C64]

Bought an ipod recently but the batt is on it's last legs it's a 3rd gen player.Has anyone got any recommendations as to which are the best brand or battery to buy I don't want to get a duffer.I take it 1200mAh is what I am after as some of them are 600-800 odd ? Thanks

Yeah, the higher the mAh the better.
As to brand, just look at feedback on a popular auction website and see which ones rate high.
I've swapped batteries on 3g's and its a very easy process. hope it goes well.
