Why doesn Apple make the battery easily replaceable? Or use different batteries, like AA?
Because if they did either, the size of the batteries and/or the access panels and mechanisms required to access the battery would make the unit significantly larger than it is, likely by several millimeters in thickness at a minimum, and would also affect other dimensions, as well as weight. It was an engineering decision to use an integrated battery; if it were not integrated, the unit would not have the small, sleek form factor that makes it so attractive in the first place. Additionally, the iPod’s battery is indeed replaceable.

Belkin makes an external battery pack for the “dockable” iPod that takes 4 standard AA batteries. Battery Tech also makes a high-capacity external rechargable battery. Big Wave Power makes a universal high capacity external battery and charging pack.
