6V 4.5ah SLA AGM VRLA Storage Lead Acid BatteryGenerally Features: 1.Long battery life, high capacity, Superior of recovery after discharge.
2. ABS material: increase the strength of battery container. (Flame-retardant ABS is optional)
3. High purity raw material: ensure low self discharge rate.
4. Silver- coated copper terminals, brass insert terminals and lead terminals improve the electric conductivity.
5. Pb CaSn alloy for plate grids: less gassing, less self-discharging high quality.
6. Maintenance-Free Operation
7. Low Self-Discharge
8.Safety valve installation for explosion proof.
