1. When charging, connect the positive electrode of the battery to the positive electrode of the power supply, and the negative electrode of the battery to the negative electrode of the power supply.

2, the initial charge is divided into two stages: first, the initial charge current is charged to the electrolyte to release bubbles, and the single cell voltage rises to 2.3-2.4V. Then the current is reduced to 1\/2 of the initial charging current, and continues to charge until the electrolyte releases violent bubbles, and the ratio and voltage remain stable for 3h. The full charging time is about 45-65h. The temperature is controlled at 35-40 ° C, and when the initial charge is completed, if the specific gravity of the electrolyte is not specified, the application of distilled water or electrolyte with a specific weight of 1.4 is adjusted.

Charge 2h after adjustment until the proportion meets the requirements. The new battery often cannot reach the capacity after the first charge, and the discharge cycle should be carried out. Discharge with 20h discharge rate (that is, discharge the rated capacity of 1\/20 of the current to the single cell voltage to 1.75V), and then add the charging current until sufficient, after a charge, discharge cycle if the capacity is still lower than 90% of the rated capacity, should be a charge, discharge cycle.

3, the charging process should often measure the electrolyte temperature with the current halving, stop charging or cooling method, the temperature is controlled at 35~40℃, the initial charging is completed, if the specific gravity of the electrolyte is not specified, the application of distilled water or the specific gravity of 1.4 electrolyte to adjust. Charge 2h after adjustment until the proportion meets the requirements.

How to quickly charge the car battery? Is it unloaded or directly charged (photo source: Photo network) Is the car battery unloaded or directly charged?
< br >
The car battery loss, it is recommended that the battery be removed, sent to a professional place to charge, do not save trouble, directly charge in the car, which will damage the car's electrical system, if you are worried about the car power after the occurrence of anti-theft system lock, audio lock, restore to the original factory Settings and other failures, you can remove the battery before connecting a spare battery to the electrical system. Then disconnect the power supply, so that the car's electrical system always has power supply.
