Does a battery supply DC or AC power?

A battery can supply either DC or AC power, depending on the type of battery it is. Direct current (DC) is when the current flows in one direction only. A battery operates on DC power, meaning that it produces a constant current flow in one direction.

Can a battery be recharged with a DC power supply?
