General Purpose Sealed Lead Acid (AGM) Batteries  1.Using oxygen recombination technology: maintenance-free 2.PbCaSn alloy for plate grids: less gassing, less self-discharging 3.High quality AGM separator: extend cycle life and prevent micro short circuit 4.ABS material: increase the strength of battery container. (Flame-retardant ABS is optional); 5.High purity raw material: ensure low self discharge rate 6.Silver-coated copper terminals (T1, T2 terminal), brass insert terminals and lead terminals improve the electric
