Q: battery problem

Don't understand question...  If you lost your USB docking cable, you'll need to get a replacement.  No way charge the device's battery without a docking cable.

Again, if you don't have your USB docking cable, there's no way to charge the battery (to use iPod or even test if the battery still holds a charge).  So, your first step is to get a new docking cable (or borrow one from a friend).
