Introduction to the correct charging method of car battery

There are more and more electric devices in today's cars. When using these electric devices, car owners should try not to overload the battery. Overloading of the battery will reduce the life of the battery. Therefore, it is very important to master the correct battery charging method: 1. First, 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 of the power supply. 2. The initial charging is carried out in two stages: first, the initial charging current is used to charge until the electrolyte releases bubbles, and the single cell voltage rises to 2.3~2.4V. Then reduce the current to 1/2 the initial charging current, continue charging until the electrolyte releases violent bubbles, and the sign and voltage remain stable for 3 hours. The total charging time is about 45~65h. 3. During the charging process, you should always measure the electrolyte temperature by halving the current, stop charging or cooling, and control the temperature at 35~40°C. When the initial charge is completed, if the electrolyte specific gravity is out of specification, distilled water or 1.4 The electrolyte is adjusted. After adjustment, charge for 2h until the specific gravity meets the regulations and on time. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
