2V 500Ah Maintenance Free Terminal OPzV Tubular storage Battery

1. Electrolyte: gel electrolyte uses imported silica, special tenichnics make it in a gel immobilized state, safer than AGM type battery;

  special additives make it very stable, lower internal resistance and no stratification;

2. Positive plate: tubular type ,with die- casting thick Pb-Ca grid; it has very good corrosion resistance and a very long service life;

3. Negative plate: pasted flat type, radial grid design ,good high rate discharge performance;

4. Separator: PVC-SiO2 separator imported from Europe, low internal resistance, high pore rate and long life;

5. Flooded electrolyte design: contain more electrolyte like a floodedbattery, space between plates and separators is full of electrolyte

  thus means good heating capacity and avoid "thermal runaway";

6. Safety valves: good sensitivity, safe and reliable , equipped with double flame arrester/acid filter;

7. Battery case: made of high strength ABS and durable design.

>Competitive Advantage
