 POWER KINGDOM 12V 4AH lead acid battery Battery 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 theelectric conductivity
