GFMJ series gel batteries utlize advanced battery manufacturing technology. It has good cyclic and high-low
temperature performance, special electrolyte design and good charge acceptance ability. GFMJ can be used in
high-low temperature environment with poor grid condition. It is optimal for pure cyclic solar, wind and energy
storage systems.
