VRLATechnology
The electrochemical reaction of batteries in charge and discharge process as follows:
Discharge
PbO2 +2H2SO4 + Pb PbSO4 + 2H2O + PbSO4
Charge
In the final stage of charge process, active substance in positive plate transformed to lead dioxide,
negative plate has not reached fully charged stage, the process of active substance in negative
plate transformed to spongy lead has not finished, oxygen gas generated in positive plate reaches
the negative plate through separator pores and reacts active substance in negative plate, resulting
depolarized state in negative plate, and restraining the generation of hydrogen.
Principle of the oxygen reduction cycle follows:

Chapter II: Electrical Characteristics
Discharge Characteristic Curve
The battery capacity is directly related to the discharge current, end voltage and discharge
temperature. In general, the smaller discharge current, the lower end voltage, the higher
temperature will cause larger discharge capacity. Figure 2-1 is the discharge curves of GFMG
Series at different discharge rate at ambient temperature 25℃.Table 2-2 is constant current
discharge data, customers could choose battery accordingly.

Charge Characteristic Curve
Figure 2-2 is the battery charge characteristic curves with constant voltage of 2.35V / cell, limited
current of 0.1C10 A, Charge the battery for 25 hours after fully discharged battery and the charged
capacity can be as high as the 104% of the discharged capacity.
