Car new battery charging correct operation method Pay attention to the positive and negative poles of the power supply and battery, strictly follow the instructions: the positive pole of the battery is connected to the positive pole of the power supply, 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.
