Batteries are an essential part of automobiles and can be divided into traditional lead-acid batteries and maintenance-free batteries.
Because the battery uses a lead-calcium alloy as the grid frame, the amount of water decomposition and water evaporation during charging is small, and the sealed structure of the casing also releases little sulfuric acid gas, so it is compared with traditional batteries , Has the advantages of no need to add any liquid, butt terminal, long storage time, etc.
