I have a 30GB 5th gen Video Ipod, I have used it so much that the battery life was down to about 30 minutes on a full charge, I dropped by Bestbuy (Geek Squad) to see what they would charge for a replacement battery and was quoted $79 !!!. I bought a 760mhz (or what it is called) battery online which is about twice the strenght of the original one for $14.95, It came yesterday morning.

Replacing the battery yourself is not recommended unless you have a sense of what you are doing. it took me about 10 minutes to replace (how 2's can be found online) where after I charged the battery for 5 hours.

It has now been playing for 11 hours ELEVEN FRIGGIN HOURS!!! and still shows 1/4 juice left. I am a happy camper
