の容量を有していた。That is, eight clad anode plates whose mandrel shoulders were coated with polyethylene in advance were stacked alternately with nine regular cathode plates with separators interposed therebetween. Prepare a comb-shaped mold,
This was placed on the edge of each electrode plate. By pouring molten lead into the mold to form a strump, the anode plates and the cathode plates were electrically connected to each other at the upper ends of their ears. The pole pole was set in the mold in advance, so that it would become integrated with the strap when pouring the molten lead. The exposed lead portion of the electrode group thus obtained, from the anode strap to the anode column, was heated to 300 to 350° C. with hot air, and then immersed in a suspension of polyvinyl chloride particles. After lifting, the tube was further heated with hot air at 300 to 350.degree. C. for 2 minutes to form a vinyl chloride coating on the anode strap and the anode column. Thereafter, unnecessary portions of the coating on the tip of the anode column were removed. This was stored in a battery case and covered with a battery case lid to form a single battery. This battery is 390AH15HR

Further, the amount of precipitate was 1 in the conventional battery B, and the ratio in the battery A according to the present invention was 0.67. In both cases, the cause of the decrease in capacity was a short circuit caused by sponge-like lead on the cathode plate; in conventional battery B, short circuits occurred at the top and bottom, and in battery A according to the present invention, short circuits occurred at the bottom.
