Comparative results of the tests of the sealed nickel-cadmium batteries for capacity safety during long-term storage after charging with direct and asymmetric currents are represented. Charging with asymmetric current was carried out in an accelerated manner at average value of the charging current equal to 0.8Crated. Charging with direct current was carried out at average value of the charging current equal to 0. lCrated in accordance with Technical Conditions.

The research results of the sealed nickel-cadmium storage batteries reliability at the rapid charge with asymmetric current are represented. In accordance with the reliability theory postulates, the experimental data of the resource test in the mode of the storage batteries 10NKGZ-1,8-1, 10NKGZ-3,5-l, 10NKGZ-4 cycling.

The comparative results of nickel cadmium storage batteries capacity regeneration with asymmetrical and direct currents after their exploitation on the electric locomotives in the conditions of constant floating with current impulses are represented. The capacity regeneration with asymmetrical current was carried out rapidly, the battery was restored with charging capacity numerically equal to 1.2C_nom.

This paper is the conclusion to the series of the articles devoted to the problem of accelerated charging of a lead-acid battery. In this paper we investigated the possibility of increasing the charge efficiency by applying the asymmetric current at the second stage. In addition, the effect of using admissible charging rates on the resource, the admissible number of consecutive cycles, and gas release were studied.
