Pb-Ca PLATE
Generally, there are two types of plates, Pb-Ca plate and Pb-Sb plate. Pb-Sb plate battery, the Sb dissolved in acid electrolyte, forms microcells with active materials at negative plate and speeds up battery self-discharge. Pb-Ca plates have better resistance to corrosion and reduce self-discharge rate. Besides, Pb-Ca alloy is featured with high hydrogen evolution overpotential, it slows down battery water loss due to less hydrogen generated from lead plate and improves battery cycle life.

Advantages of Pb-Ca plate
1.    Low self-discharge rate.
2.    Sufficient Capacity.
3.    Low water loss.
4.    Strong corrosion resistance.
5.    Great Mechanical strength.
6.    High conductive rate reduces power loss and improves starting power.
7.    Excellent power reserve ability.

All our motorcycle batteries adopt Pb-Ca plates. From lead ingot purchasing to finished plate, the whole processing line is rigidly conform to the GB/T organization standard.

QUALITY CONTROL:
To ensure every process, we have established a series of QC stations which cover from incoming raw materials to final shipment. To assure stable and high quality, our QC team continually tests all finished products strictly adhered to JIS Standard as below:
Capacity Test ( 10Hr rate)
0° F / -18° C Cold Cranking Amps (CCA) Test
Reserve Capacity Test
Low Temp High Rate Discharge Test
Dry Charge Test
Cycle Life Test
