FIELD: electricity.
SUBSTANCE: invention is used in alkaline accumulators comprising a positive electrode from spherical nickel hydroxide and negative electrode from zinc oxide which are divided by combined porous separator, alkaline electrolyte and cell jar with valve. In order to absorb released gases and ensure long life of the accumulator valve with opening pressure of (3.0-3.5)·102 kPa is used providing for the stabilisation of total gas pressure at the level of (1.0-1.2)·102 kPa.
EFFECT: long life of the accumulator in sealed state.
