Page 5: Vrla Technology
VRLA Technology 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 fully transformed to lead dioxide, negative plate has not reached fully charged stage, the process of active substance in negative plate transformed 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 6: Chapter Ii: Electrical Characteristics
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 DCS Series at different discharge rate at ambient temperature 25℃. Table 2-1 describes the end voltage at different discharge rate. -
Page 7: Charging Characteristic Curve
Charging Characteristic Curve Figure 2-2 describes the battery charge characteristic curves with constant voltage of 2.35V / cell and limited current of 0.1C A. When charging the battery for 24 hours after fully discharged, the charge capacity can be as high as the 104% of the discharged capacity. Figure 2-2 Charge characteristic curve Cycle Performance Curve At different depth of discharge, the battery cycle life is different, in general, the more shallow depth... -

Page 11: Temperature Effect On Battery Capacity
25℃ to 35℃, capacity will be approximately 105% of the nominal capacity. From 35℃ to 45℃, the capacity increase is very low and if temperature rises beyond 45℃, there is no increase in battery capacity. Figure 3-1 DCS series temperature effect on battery capacity curve... -
Page 12: Temperature And Floating/Equalizing Charge Voltage
Temperature Effect on Battery Design Life Temperature range of the DCS series is -20℃~+75℃. The battery can be used in 15℃~40 ℃ environment for a long time. Corrective measures should be taken in case the temperature deviates from the optimum temperature range. -
Page 13: Storage
Storage Storage Interval: Battery should be stored in fully charged state. It is strictly prohibited to storage after discharge. Battery storage location must be away from heat, sparks and smoke. Battery must be stored in an upright position, avoiding impacts of external force or abrupt loads. Safety valve should be tightened. -
Page 14: Maintenance
Maintenance 1. Cleaning Notes: Battery appearance, terminal area and working environment must be kept clean and dry. In battery cleaning process, avoid use of electrostatic cleaning tools. Clean the battery with damp cloth. Do not use of gasoline, alcohol or other organic solvents; also do not use cloth containing these substances. - Page 15 Item Content Standard Maintenance Use hex or torque Securely connected If found bolt loosened, tighten it wrench to tighten loose bolts. 1-Battery cables, No evidence of If slight corrosion found after connecting terminals clean / corrosion bar removed, clean it with cloth. If severe 4- Joints non-corrosive.
