Abstract

PURPOSE:To improve the cycle life of a lead-acid battery by limiting the specific gravity of the electrolyte during discharging below a prescribed value in a maintenance-free battery with a lead alloy grid containing prescribed amount of Sb. CONSTITUTION:For a maintenance-free battery in which a positive grid of lead alloy containing 0.5-2.3wt% of Sb is used and more than 1.2cc. electrolyte per 1g. of positive active material is retained, the specific gravity of the electrolyte is limited as mentioned below. The specific gravity of the electrolyte reduced to 20 deg.C is not more than 1.3 at full charged state, and in the 5hr. capacity test the spefific gravity is not more than 1.19 for a grid of lead alloy containing 0.5-2wt% of Sb and not more than 1.2 for lead alloy containing 2-2.3wt% at the condition after 2hr. discharge.
