Batteries are widely used in daily life, and can be divided into traditional lead-acid liquid-filled batteries and maintenance-free batteries. Because the batteries use lead-calcium alloy as the grid, the amount of water decomposition generated during charging is small, and the amount of water evaporation is also low. , and the casing adopts a sealed structure, and the sulfuric acid gas released is very little, so it has the advantages of no need to add any liquid, docking the wiring pile head, and long power storage time compared with the traditional battery. Batteries have a life cycle, different usage conditions, different environments, and different service life. Today, let’s understand what reasons will affect the service life of the battery?
