1) Maintenance-Free Operation
Absorbent Glass Mat (AGM) technology ensures efficient gas recombination up to 99% and freedom from electrolyte maintenance. During the expected service life of batteries, no need to check the specific gravity of the electrolyte or add water.
2) Good Discharging Ability
Tight assembly technology ensures an excellent high-rate discharge performance.
3) Long Service Life
A unique corrosion-resistant grid alloy ensures batteries have long service life.
4) Low Self Discharge
Using high purity raw materials ensures batteries have less self-discharge.
5) Environmental & Non-polluting
Gas Recombination technology ensures the battery high seal reacting rate, which can prevent the acid fog from separating out.
6) Safe & Reliable
Efficient venting system automatically release excess gas when the pressure rises above the normal level & reseals the valves when it returns to the normal rate, which can protect the battery from bursting.
