A variety of electrode plates having different thicknesses before being pressurized were prepared by interposing them between the negative electrode plate groups, and the thickness when each of them was pressed at a constant pressing force, that is, 20 kg / dm 2. The different compression electrode groups are incorporated in each cell chamber of each of the above-mentioned battery cases,
For each of the lead-acid batteries, an electrolytic solution was injected into each cell chamber according to a conventional method, and the battery case lid was airtightly applied to produce each sealed lead-acid battery. As a result of testing the discharge characteristics, the thickness of the compressed electrode group /
