As a big battery manufacturers in China, we supply many different kinds of batteries , such as the lead acid AGM battery , Gel battery , Deep cycle battery , OPzV Tubular battery , OPzS Tubular battery ..etc .

The following is our 12V 55Ah Lead Acid Battery features :

1. Using oxygen recombination technology: maintenance-free

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

3. High purity raw material: ensure low self discharge rate

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

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

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

7. Advanced lead tin calcium alloy, reduces grid corrosion & promotes long battery life

8. Oversized partition intercell welds, providing low resistance connections & minimal power loss
