• Using oxygen recombination technology: maintenance-free

• PbCaSn alloy for plate grids: less gassing, less self-discharging

• High quality AGM separator: extend cycle life and prevent micro short circuit

• ABS material: increase the strength of battery container. (Flame-retardant ABS is optional);

• High purity raw material: ensure low self discharge rate

• Silver-coated copper terminals (T1, T2 terminal), brass insert terminals and lead terminals improve the electric conductivity
