Product Description

>Main Features

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 conductivity
