FIELD: electricity.
SUBSTANCE: to each accumulator of storage battery there supplied during 30-90 s is charge voltage exceeding by 0.05-0.50 V or open circuit voltage or charge voltage, and charge current is measured. Then, measured charge currents are compared. The more the charge current of any accumulator in comparison to other accumulators in battery, the lower the capacity of this accumulator is.
EFFECT: diagnostic method of state of individual non-tight nickel-cadmium accumulators gathered into a battery is simplified.
