FIELD: physics.
SUBSTANCE: sealed rectangular accumulator battery has an electrode group consisting of positive and negative electrodes, and a galvanic cell housing which accommodates the electrode group and an electrolyte solution, wherein the housing has a rectangular frame element, a first cover element and a second cover element. Each of the two cover elements includes a housing part which covers one of the holes of the frame element outside the battery, and a lateral part which protrudes from the housing part at least along one pair of sides opposite each other.
EFFECT: excellent properties with respect to volume efficiency and pressure resistance.
