Abstract

A lead-acid battery 1 includes: a battery case 10; electrode plates 30A and 30B housed in the battery case 10; an electrolyte solution U housed in the battery case 10; and a vent plug 70 attached to the battery case 10, in which the vent plug 70 includes a tubular plug body 71, a splash guard 90 positioned inside the plug body, and a plurality of catalytic devices 100A, 100B, that promote reaction generating water from gas produced by charge-discharge reaction. Each of the plurality of catalytic devices 100A, 100B include a tubular case 110 with an open front surface, a catalyst layer 120 housed in the case 110, and a permeable membrane 130 covering a front surface of the catalyst layer and allowing gas to pass through. Each of the plurality of catalytic devices 100A, 100B are arranged vertically or inclined with respect to the plug body 71 so that a front surface provided with the permeable membrane 130 has an angle with respect to a horizontal direction. In an up-down direction, either all or at least a part of the plurality of catalytic devices 100A, 100B is arranged at the same height.
