ABSTRACT OF THE DISCLOSURE A battery charging system having a charger control circuit which monitors one cell of a battery bank and controls the operation of a charging current source in accordance with the terminal voltage of the monitored cell. The charger con- trol circuit includes an overcharge sensing circuit and a shorted cell sensing circuit, each being capable of triggering a separate output driver to interrupt current flow from the charging current source to the battery bank. The overcharge sensing circuit employs a time delay network to avoid nuisance charger system interruptions. The shorted cell sensing cir- cuit also employs a time delay network to allow charging of heavily discharged or zero voltage batteries.
