Morphology

discharge = charge (transparent) = dis + charge

This is a clear reversative use of 'dis-' with 'charge', meaning to remove the electrical charge that has been put into something.

Etymology

Discharge in electricity comes from the same idea: dis- 'off' and charge as the electrical load, so to discharge a battery is to let its electrical charge go.
