The sealed lead-acid battery with pasted positive plates has been used for electric vehicle propulsion. Because of an insulating layer of PbSO4 formed between the surface of positive plate grids and active materials, and the expansion and shedding of lead powders, early failure of lead-acid batteries during deep cycling is obvious. Hence, it is a limit to the long-term usage of the sealed pasted type lead-acid battery. We adopt a new type alloy (OLSB-80) to make grids of the oval turbular positive plates, and have constructed a sealed lead-acid battery using the oval turbular positive plates. We have not found out that this battery capacity los during initial 540 cycles (DOD60 %). In addition the weight energy density of such battery is higher than 36Wh/kg at 5 hour rate, the high rate discharge time (at 1 C5) is more than 34 minutes, the gases recombination efficiency is about 97 %.
