A voltage responsive cut-off circuit cuts off the charging current supplied to a battery by a variable direct-current source when the terminal voltage of the battery reaches a preselected value. The cut-off circuit is voltage-responsive and includes circuitry for limiting the current flow there through to prevent burning out the elements and further includes circuitry for bypassing the transient voltages so that the cut-off circuit will be responsive to the true direct-current voltage level across the battery. |
