The following is our 12V 250Ah Lead Acid Battery features :

General 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
