Study on lead-acid battery for deep cycle application

Effects of the alloy for positive plate, the additives in negative plate and the proportion of positive grid to negative grid on the cycle life of lead acid battery were studied. The results show that cycle life is improved by the addition of Cd in Pb Sb and Pb Ca alloys, and the battery with the Pb Sb Cd alloy as positive plate has the longest cycle life. The appropriate content of additives in negative plate is the key factor for improving the low temperature performance and the charge acceptability of lead acid battery. That is, low content causes the bad low temperature performance while high content results in the poor charge acceptability. Moreover, the cycle life of battery is increased by the proper proportion of positive grid to negative grid.
