Replacement 3.7V 400mAh Li-Poly Battery for iPod NANO 1st - Silver + Gold

Pros: Gave a new lease of life to my old and (battery) failing ipod nano. Fits perfectly. Not to difficult to install if you know how to do some simple soldering. Has more rated juice than the installed battery 400mah vs 330mah but i've not tested whether does it really translate to more playing hours. But it's definitely better than the old battery.

Cons: none i can think of

Other: Great replacement battery

Pros: + Really cheap replacement
+ Last about 10 hours when it's full charged (I tested several times and every time lasted about 10 hours)
+ Nice build quality

Cons: - Only bad side that I can think of is a battery life, it could last longer (Apple's battery last 14 hours), but it 10 hours is more than enough
- I don't see any more cons!

Other: It's really worth of money. Great if you have an old iPod Nano that just sitting somewhere because of dead battery.

Pros: It's a good option to extend the life of my iPod nano 1st generation. In times like these, when you need to know what to spend the money best, is a good alternative renew iPod battery before buying another.

Cons: No cons, it's a great item.

Other: The battery is of high quality, just have to remove the metal casing of the iPod with a screwdriver or a flat element, unsolder the old battery and solder the new one to re-adjust the lid and close the iPod.
