PURPOSE:To avoid the deterioration of battery capacity while maintaining the merit of a lead acid battery which contains a lead-calcium-system-alloy grid, by using a positive plate made of a lead-calcium system alloy and a negative plate made of a lead-antimony system alloy. CONSTITUTION:An assembled element 1' is constituted of positive plates 3' made of a lead-calcium-system-alloy grid which contains 0.1% of calcium, and negative plates 4 made of a lead-antimony-system-alloy grid which contains 2.5% of antimony, and a separator which is placed between these negative plates 4. The end plate of the assembled element 1' should be the positive plate 3'. |
