FIELD: electricity.

SUBSTANCE: invention is related to a lead-acid battery of hydroelectric type comprising a container that includes a pack of plates received by stacking of negative plate with negative active material filled to the negative current collector, positive plate with positive active material filled to the positive current collector and a separator placed in-between; and electrolyte. At that charge is performed periodically while high-speed charge to the load is made in partial charge state. To negative active material at least carbon electroconductive material and organic compound is added; the compound is capable to suppress coarsening of the negative active material in result of charge and discharge and positive plates have the total surface area [m²] of the positive active material per a volume unit of the plate pack [cm³] within the range of 3.5-15.6 [m²/cm³].

EFFECT: usage of this invention allows improvement of charge receiving characteristics and service life of the battery.
