Features: GFM series VRLA sealed batteries is not necessary to refill with water, all the gases generated during charge are recombined internally, being incorporated again to the electrolyte;safety valves, they release to the outside any overpressure that can be generated internally, so that no emission of gases will occur, safty can be ensured by incorporating an explosion proof filter in the vent hole section;self-discharge, the self-discharge rate has been decreased because of use of pb-ca alloy so that it is unnecessary to charge the battery till half year if place in storehouse at room temperature;safety and sealing, the acid will not leak from the area around the terminal and container, so that the operation can be safe and effective, the battery can be placed horizontally; long service life,long service life has been attained by use of pb-ca alloy, more than 10 years of service life can be expected if use under floating charge.

The vented lead-acid stationary batteries is widely used in the electric power, telecommunication and UPS system, in accordance with the basic parameter and electric performance of DIN standard.GGM stationary battery is a set with a device of acid mist restriction. GGX stationary battery with catalysis plug.Safety, long service life, reliability in service and maintenance easy are typical characteristics.
