Beschreibung
Zusammenfassung:	In order to extend the useful life of electrical storage battery cells under float voltage charge it is advisable to maintain the polarization of the positive plates of the cell relative to a reference electrode in the cell at a predetermined level. This invention provides a sensing and controller circuit which drains minute amounts of current from the positive cell plates when the polarization rises above the desired level and thereby prevents plate corrosion and loss of electrolyte. The present invention may be combined with a circuit for increasing cell polarization levels to provide a system for maintaining battery cells at optimum polarization levels over extended float charging periods.
