Car battery charging method

Connect the positive pole of the battery to the positive pole of the power supply and the negative pole of the battery to the negative pole

The initial charging is carried out in two stages: first, the initial charging current is charged to the electrolyte to release bubbles, and the cell voltage rises to 2.3 to 2.4V. Then, the current is reduced to 1/2 initial charging current, and the charging is continued to the electrolyte to release a vigorous bubble, which is stable for 3 consecutive hours. The total charging time is about 45~65h.

During the charging process, the temperature of the electrolyte should be measured by halving the current, stopping charging or cooling. The temperature is controlled at 35~40 °C. When the initial charging is completed, if the specific gravity of the electrolyte is not specified, distilled water or electrolysis with a specific gravity of 1.4 is applied. The liquid is adjusted. After adjustment, recharge for 2 hours until the specific gravity meets the requirements.
The new battery often fails to reach capacity after the first charge, and a discharge cycle should be performed. Discharge at a discharge rate of 20hh (ie, discharge with a current of 1/20 of rated capacity until the voltage of the single cell drops to 1.75V), and then replenish the charging current enough. After a charge and discharge cycle, if the capacity is still lower than the rated capacity of 90 At %, a charge and discharge cycle should be performed again.
