Correct charging and using method of new car battery

First, the most basic thing is to connect the positive battery to the positive battery and the negative battery to the negative battery. The initial charging is carried out in two stages: First, use the initial charging current to charge the electrolyte, release bubbles, and intermittently increase the single cell voltage to 2.3-2.4v. Then the current is reduced to 1/2 of the initial charging current, and the charging is continued until the electrolyte releases strong bubbles. The charging time is about 45~65h. In the charging process, the current should be halved, intermittent charging or cooling methods should often be used to measure the temperature of the electrolyte. The temperature should be controlled at 35~40℃. At the end of the initial charge, if the specific gravity of the electrolyte is not specified, distilled water or an electrolyte with a specific gravity of 1.4 should be used for adjustment. After adjustment, charge for 2h until the specific gravity reaches the requirement. New batteries after the first charge are often not up to capacity and should be discharged in cycles. The discharge rate is 20hh (that is, 1/20 of the rated capacity is discharged to a single cell voltage of 1.75v intermittently), and then sufficient charging current is made up, through the charge discharge cycle, if the capacity is still less than 90% of the rated capacity, it should be Charge and discharge cycle.
