A battery that is ready for use is already "on" as we understand it. The chemical reactions that provide the difference of potential are "ready to go" and drive current flow. It remains for the operator to make the final connection, like the flipping of a switch, to complete the circuit so the current will have a place to flow. The voltage, which is electromotive force, or the force that will cause electrons to flow, is present on the terminals of a good battery. This voltage will be present across the poles of the open switch, too. Close the switch and current flows. The battery was already "on" and waiting for a circuit to appear so it could force current through it.
