GFM-XC series cycling long-life LA battery is a high-tech product, which developed independently by COSLIGHT. It can be widely used at II or III class power supply areas for telecom system, EV and etc. Compared with the previous generation VRLA battery, the cycle life of the 6-GFM-XC series battery can be raised more than 60% at 100% DOD.


GFM-XC series adopt lead-calcium alloy material with adding corrosion-resistant X additives, which improves decay resistance performance of grids greatly.


The battery adopts special positive active material additives and electrolyte additives. Raising the life of active material additives and restraining electrolyte layering make a great improvement for cycle life of the battery.


The battery adopts high elastic superfine fiberglass separator to reach closed assembly, and get a great improvement for cycle life of the battery.
