ABSTRACT:
An automatic shut-off battery charging system which employs a timing control circuit (TC101) to initiate intermittent monitoring of the equivalent internal resistance of a load battery (B101) under charge, and a comparison circuit (PD101) which disables charging when the internal resistance indicates that the battery is charged to capacity.
