ABSTRACT:
A charging circuit for charging a DC cell is provided. A supply circuit produces a charging current at a first selected value and a current gating circuit is disposed intermediate the DC cell and the supply circuit for selectively applying the charging current produced by the supply circuit to the DC cell. A control circuit is coupled to the DC cell and to the gating circuit, the control circuit being adapted to detect when the cell is charged to a predetermined maximum voltage, and in response thereto control the gating circuit to prevent the charging current from being supplied to the DC cell. The control circuit is further adapted in response to a drop in the voltage of the cell to a second predetermined level, to control the gating circuit and thereby permit a charging current of a second value reduced with respect to said first value to be applied to the DC cell.
