Resumen
The stand of the check and diagnostic of a technical state of accumulators designed. Methods of measuring of performances of accumulators are spotted. The method of the non-destructive check at which performances of accumulators are measured on an alternating current is recommended. Duties of the stand recovery of a technical state of accumulators are offered by a desulphation charge with the subsequent cycling for lead-acid accumulators and regimes of penetrating discharge for elimination of a memory effect at nickel - cadmium accumulators.
