Five misunderstandings about the length of service life and winter maintenance of batteries

The service life of an automobile battery is not only determined by the structure and quality of the battery, but also closely related to its operation and maintenance.

Generally, the service life of a car battery is about 2 years, and if properly maintained, it can reach 3 to 4 years. At present, there are still many misunderstandings in the maintenance of the battery, which leads to the early damage of the battery.

Misunderstanding 1: When using maintenance-free batteries, simply think that maintenance-free means that no maintenance is required.

Misunderstanding 2: Corrosion on the surface of the battery pole post does not need to be dealt with, as long as it is not loose. Corrosion appears on the surface, and corrosion occurs on the inner surface of the terminal, resulting in an increase in the resistance value, affecting the normal charging and discharging of the battery, and must be dealt with in time.

Misunderstanding 3: When the liquid level is low, supplement the electrolyte or add drinking pure water instead of the required distilled water. If the electrolyte containing sulfuric acid is added, the concentration of the electrolyte inside the battery will increase, and phenomena such as boiling and acid mist may occur, which will seriously affect the service life of the battery. Use pure drinking water instead of distilled water. Pure water contains a variety of trace elements. , adversely affect the battery.

Misunderstanding 4: The density of the electrolyte is not checked and adjusted, especially when winter comes, resulting in insufficient battery capacity and even the phenomenon of electrolyte freezing.

Misunderstanding 5: When using the battery to start in winter, use the starter without interruption, which will cause the battery to be damaged due to excessive discharge.
