Comparative results of capacity renewal of sealed nickel-cadmium batteries with asymmetric and direct currents after their long-term storage are represented. Capacity renewal with asymmetric current was carried out in an accelerated manner at average value of the charging current equal to 0,25C_rated. Capacity renewal with direct current was carried out at average value of the charging current equal to 0,1C_rated in accordance with Technical Conditions.

The results of nickel cadmium accumulators (NCA) formation with the asymmetric and constant currents are represented. Accumulators formation with the asymmetric current allowed to reduce one-half the time of technological cycle of placing these accumulators in service, comparing with the constant current mode, with maintenance of their operational characteristics. Comparative characteristics of NCA operational parameters are given.

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.
