Ring battery charger, by individual cell or group of three cells-for discharge capacity enhancement

Three methods are described for providing increased float voltage levels to lead acid cells, while maintaining output line voltage at acceptable or well regulated levels. The first is a momentary boost of individual cells, one at a time, the second is a momentary boost of three cells, one group at a time, and the third method is a momentary 'blast' of individual cells, one at a time. It is estimated that these techniques can add as much as one hour reserve capacity to the average string, with little additional cost.<
