lead-acid batteries

The capabilities of our designed charging device for charging of lead-acid batteries with sulfated plates by pulse asymmetric current were tested experimentally. The principle of the considered charging mode is based on alternation of short high-amplitude pulses of the charging current with discharging current pulses with their sequence frequency being multiple of the alternating current frequency in Russia (50 Hz).

This article is dedicated to the investigation of sulfatation process of negative active mass. The authors showed a dependence of sulfatation degree of lead electrode from time of keeping in discharged station. It was studied the influence of addition of ammonium sulfate on desulfatation process.
