The charge system is automatically connected when the charge on the battery reaches a predetermined minimum, and disconnected when it is charged to a predetermined maximum. The battery in each case is connected with the usual utility source of AC, and upon the voltage of the battery reaching the levels mentioned, the AC source is respectively connected or disconnected.
