>Product Feature
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.
>Battery use and maintenance:
1) Please use constant-voltage charge;
2) In floating charge, the voltage is 2.23 to 2.27 per unit cell;
3) In cycle use, the voltage is 2.35 to 2.45 per unit cell, the max. Current is no more than 25%° C;
4) Please do tighten the bolts to avoid sparkle and poor contact when the battery is in use;
5) Please do not use it near the heat source and open flame;
6) Please keep it at low temperature;
7)Please change it while there is liquid leaking or damage.
