VRLA gel and AGM batteries offer several advantages compared with VRLA flooded lead-acid and conventional lead-acid batteries. The battery can be mounted in any position, since the valves only operate on over-pressure faults. Since the battery system is designed to be recombinant and eliminate the emission of gases on overcharge, room ventilation requirements are reduced, and no acid fume is emitted during normal operation. Flooded cell gas emissions are of little consequ…
