A method for producing a metallic oxide-hydrogen secondary battery is provided. The method comprises the steps of disposing generating elements consisting of positive electrodes containing metallic oxides, negative electrodes containing hydrogen-absorbing alloys, and separators in a plurality of cell chambers equipped with safety valves, each cell chamber having different capacity; pouring an electrolyte into each cell chamber; and repeating charge and discharge cycles on condition that safety valves work at pressure G in the range of 1&lt;G.ltoreq.6 atm so that the amount of the electrolyte in each cell chamber is kept constant.

A dry cell of the type enclosing therein an electrolyte mainly consisting of zinc chloride, wherein in order to ensure the more secure air- and liquid-tightness a filler or sealing agent is filled into the space between a plastic top seal and a metal top seal to seal a carbon electrode extended out of the plastic top and the upper end portion of a plastic tube covering the top surface of the plastic top seal, whereby the longer shelf life may be ensured.
