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.

The most important structural and physicomechanical properties of absorbent glass mat separators «Hollingswoth and Vose», «Bernard Dumas», «BMSK AT Nippon» intended for lead-acid battery (LAB) are studied. It is shown that on pore size distribution strong influence puts the enclosed pressure: at compression 50 kPa there is a considerable reduction of the size of a pore.
