The length of service life of a car battery depends not only on the structure and quality of the battery, but also on its operation and maintenance.
The service life of a typical car battery is about 2 years. If it is properly maintained, it can reach 3 to 4 years. At present, there are still many misunderstandings on the maintenance of the battery, resulting in early damage of the battery.
Myth #1: When using maintenance-free batteries, simply consider maintenance-free without any maintenance.
Misunderstanding 2: There is no corrosive material on the exterior of the battery pole post. As long as it is not loose, it can be used. Corrosive substances appear on the surface, and corrosion will occur on the inner surface of the terminal block, resulting in an increase in the resistance value, affecting the normal charging and discharging of the battery, and must be handled in time.
Misunderstanding 3: When the liquid level is low, replenish the electrolyte or add pure water instead of the distilled water needed. If an electrolyte containing sulfuric acid is added, the concentration of electrolyte inside the battery will increase, and boiling, acid mist, etc. may occur, which seriously affects the service life of the battery; use distilled water instead of distilled water, and the purified water contains various trace elements. , has a bad influence on the battery.
Misunderstanding 4: The density of the electrolyte is not checked and adjusted, especially in the winter, causing insufficient battery capacity and even causing the electrolyte to freeze.
Myth 5: When the battery is started in winter, the starter is used continuously, causing the battery to be damaged due to excessive discharge.
