Starting use of the battery:
1 Preparation before start using
The battery leaves factory in discharged state without electrolyte. Before start using, it is needed to do following preparation:
1.1 Measure the cell’s open circuit voltage one by one. If the value is lower than 0.5V, a small amount of electrolyte can be filled in, and then measure it again. If the voltage goes up to 0.5V,it will be regarded as the qualified.
1.2Check the nut one by one whether are tightened enough.
1.3 Filling with the electrolyte
Unscrew the vent plug, fill the electrolyte into the battery in time(electrolyte standard and preparation method is shown in Appendix 1.) Adjust electrolyte level between two limit lines. Screw the vent plug again, move the sealer on the hole of the vent plug and clean the battery. The battery must be soaked for 4 hours after filling with electrolyte then adjust electrolyte level again
1.4 Place the battery in its location and connect the battery in series with connector. In the end, connect the last positive terminal with the positive lead of charger, and the negative terminal is connected with the charger’s negative lead. Mistake connection is forbidden.
