The battery will lose a certain capacity if it takes a long time during transportation, storage and installation. The parameters of the charging equipment should be adjusted correctly according to the parameters of the battery equipped. It is necessary to ensure that the float voltage and equalizing voltage are within the qualified range to ensure the normal floating charge operation of the battery, and it will not cause overcharge or overdischarge. After the parameters are set, if there is no special need, do not change them at will. When the battery needs to be replaced due to insufficient capacity, it can only be replaced all at once. The battery with insufficient performance index cannot be replaced separately, otherwise the unbalanced internal resistance of the battery will affect the performance of the entire battery and shorten the entire battery. Service life. In order to ensure that the battery has sufficient capacity, a capacity recovery test shall be carried out once a year to activate the activated substances in the battery and restore the capacity of the battery. The main method is to remove the battery pack from the charger, add an adjustable load to both ends of the battery pack, make the discharge current of the battery pack 0.1 times the rated capacity, and record the battery voltage every half an hour until the battery voltage drops to 1.8V /Only or 10.8V/Only after stopping the discharge, and record the battery operating time.
