Page 6: Working Principle
Working Principle The electrochemical reaction of batteries in charge and discharge process is as follows: Discharge + Pb PbSO + 2H O + PbSO Charge In the final stage of charge process, active substance in positive plate is fully transformed to lead dioxide, but negative plate has not reached fully charged stage, the process of active substance in negative plate transforming to spongy lead is not finished, oxygen gas generated in positive plate reaches the negative plate through separator pores and then reacts with active substance in... -
Page 7: Chapter Ii: Electrical Characteristics
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 describes the discharge curves of FAJ Series at different discharge rate at ambient temperature 25℃. -

Page 12: Factors Influencing Capacity
Battery capacity consists both of nominal capacity and actual capacity, for nominal capacities of the FAJ series battery please refer to Table 1-1. Actual capacity is the real quantity of electricity battery discharge under certain condition, it equals to discharge current multiplied by discharge time, the unit is Ah. -
Page 13: Recharge
Floating charge FAJ series batteries can be used in floating and cycle application. Floating operation is the best operation condition for the battery. In floating operation, if the battery is kept at fully charged state, the battery can reach the longest service life. At the ambient temperature of 25℃, recommended floating charge voltage setting value is 2.25V/ cell. -
