The 4th Generation iPod nano is rectangular with a curved outer case and is silver or black with a black ScrollWheel, or purple, blue, green, yellow, orange, red, or pink with a white ScrollWheel.
The battery inside the 4th Generation iPod nano is soldered to the motherboard, and is very difficult for the average consumer to replace. That’s why we don’t offer a battery replacement kit for the iPod nano like we do with the other iPod models.
This battery is guaranteed for ten years, so if it ever fails to keep a full charge during this period of time, let us know and we will give you a new one (if you purchased it to install yourself) or re-install one for you (if you sent your device to us for the installation) at no additional charge!
No other website offers this kind of coverage.
