The invention relates to a method for making an electrolytic battery which is preferably used in movable facilities such as cars, boats and planes. The method comprises the following steps: inserting of intermixing plates 5a′ into the battery case 1, one each at two sides thereof which are opposite to each other, inserting of the set of electrodes 2 between the two intermixing plates 5a′ positioned in the battery case 1 and connecting of the two intermixing plates 5a′ straightened out vertically with the bridging plate 5b′ comprising a drain surface, which is slightly inclined towards the center thereof, and an opening provided approximately in the center thereof to enable electrolyte to flow back into the batter case.
