Abstract

The capacity characteristic of VRLA batteries with different design was investigated in this paper. The possibility of discharge time raised from 130 minutes to 150 minutes for 6-DZM-10 VRLA battery at 5A had been proved. The cyclic test results showed that the battery with proper density and quantity of electrolyte had excellent performance of capacity and cyclic life. Cyclic life of battery at 5A / 100% DOD had reached more than 300 cycles. Uniformity of capacity and sulfatization of negative material had a strong impact on the cyclic life of VRLA batteries.
