METHOD OF RECOVERY OF TRACTION LEAD-ACID STORAGE BATTERIES Russian patent published in 2019 - IPC H01M10/54 

FIELD: electrical engineering.

SUBSTANCE: invention relates to a method of recovering lost capacity of accumulator batteries and prolonging their service life. Method of recovering traction lead-acid batteries comprises dismantling the battery, opening each element, elimination of damages, cleaning of the housing and positive and negative plates of elements from the slurry, assembly of elements with check for tightness by pressing, filling with new electrolyte and conducting of control-training cycles (CTC), at that, CTC is carried out on specialized charging/discharging devices imitating C5 load, at least from three charge cycles in mode of capacitance and discharges recovery with direct current as per C5 standard, wherein selection of the reduced elements is carried out by voltage drop under constant load under the condition of not more than 0.05 between elements and the battery is assembled from the selected elements.

EFFECT: technical result of the invention is improved reliability and efficiency of the method of recovering the lost battery capacity.
