Abstract: At present, the main manufacturing processes for VRLA batteries are the GEL process for a long lifetime and the AGM process which is suitable for high power discharging. Many domestic VRLA battery brands are analyzed. As a result, the high-power VRLA batteries are a new development trend all over the world, especially for the UPS market, the float charging is essential for the batteries. In this paper, the high-power VRLA batteries made by the advanced punched and expanded grids and the continuous pasted plate manufacturing technology are tested. The experimental results show that the discharge performance of high power VRLA batteries at 20 h rate constant current and 15 min constant power is better than that of the battery made of the casting grids. In addition, with the increasing time of the float charging, the voltage range of these batteries is decreased gradually, and indicating that the high-power VRLA batteries have good stability and consistency
Keywords: VRLA battery; high-power; initial discharging; float charging voltage; consistency
