I bought the battery to replace my old one and once I finally got the Ipod open, the old battery out and the new one in and tried to start up the Ipod nothing happened but I was expecting this because the instructions said it needs to charge. Then I plugged my Ipod in to charge and the Ipod came to life and said the battery was charged but whenever I unplugged the Ipod it would just shut off even after I left it charging for at least six hours. I tried reinstalling it but I still got the same thing. Then I just left the Ipod to charge the rest of the night and most of the day yet when I unplug it it just turns off and I cannot turn it on again unless I charge it. I putted my old battery back in and the Ipod turns on and works just fine.I'm extremely disappointed with the product and wouldn't recommend it. But to be fair I think it's just luck of the draw, most of the other reviews on hear have nothing but good things to say about the battery while there are a few who say that the battery didn't even work like mine. I think that there is the off chance that the occasional customer will come across a faulty battery. Like I said, luck of the draw. May the odds ever be in your favor.
