<p>A charger (2) for charging rechargeable batteries including circuitry (4) for supplying electrical charging power to said rechargeable battery so as to rapidly charge said rechargeable battery, interrupting circuitry (6) for repeatedly interrupting said electrical charging power to said rechargeable battery for a preselected timed interval so as to permit the detection of the internal resistance free voltage of said battery during said interruption of said power, electrical comparing circuitry (l0) for comparing the internal resistance free voltage of said battery with a preselected reference voltage, and electrical control circuitry (l2) for reducing said power to said battery when said internal resistance free voltage exceeds said preselected reference voltage so as to reduce gradually the rate of charging of said rechargeable battery and maintain said internal resistance free voltage of said battery at said preselected reference voltage.</p> |
