Abstract
A battery cell controlled charging system, consisting of a display unit, battery cell probes, a battery charger and circuitry for controlling the charger, monitors the specific gravity, electrolyte level and temperature control of each cell in a multi-cell lead-acid battery and uses the information to automatically charge the battery when a cell or cells become out of specification while restricting overcharging which is damaging to cells.
