Features of an AGM battery:
VRLA AGM battery uses recombinant technology. The oxygen produced from the positive plates of the battery is absorbed by the negative plates. This suppresses the generation of hydrogen at the negative plates. The recombination of oxygen and hydrogen leads to Water, retaining the electrolyte amount within the battery. Water re-filling is never required.
The advantage of AGM battery
When battery is charging, hydrogen would be absorbed and reversed to electrolyte by plates. It doesn't need to refill water and balanced charge, which makes maintenance free.
AGM separator keep electrolyte absorbed in glass mat and still. Battery can be used or positioned in any orientation.
When excessive gas production by inappropriate charging occurs, safety valves will automatically emit the gas to prevent battery cracked.
Long standby life, Better cycle performance
Anti-corrosion lead-calcium alloy plate provides longer float charging life. AGM separator can trap electrolyte and prevent active materials on positive plate dropping at the same time. Moreover, it gives better deep discharge cycle performance.
Longer shelf life
Special lead-calcium alloy plates make lower self-discharge for longer shelf life.
High rate performance
Low inner resistance allows higher discharging and charging current for better performance in high rate application
