　　Misunderstanding of usage

　　The lifespan of automotive batteries is not only determined by their structure and quality, but also closely related to their operation and maintenance. The service life of a typical automotive battery is around 2 years, and if properly maintained, it can reach 3-4 years. There are still many misunderstandings among car owners regarding the maintenance and upkeep of batteries, which can lead to early battery damage and should be taken seriously.

　　Myth 1: When using maintenance free batteries, simply believing that maintenance free means no maintenance is required.

　　Mistake 2: There is corrosion on the surface of the battery pole terminal, which does not need to be treated. As long as it is not loose, it is sufficient. Corrosive substances appear on the surface, and corrosion can also occur on the inner surface of the terminal, leading to an increase in resistance value and affecting the normal charging and discharging of the battery. Timely treatment is necessary.

　　Mistake 3: When the liquid level is low, supplement the electrolyte or add purified water instead of the required distilled water. If an electrolyte containing sulfuric acid is added, it will increase the concentration of electrolyte inside the battery, which may cause boiling, acid mist, and other phenomena, seriously affecting the service life of the battery; Replace distilled water with purified drinking water, which contains multiple trace elements and has adverse effects on batteries.

　　Myth 4: The density of electrolyte is not checked and adjusted, especially during winter, which leads to insufficient battery capacity and even the phenomenon of electrolyte freezing.

　　Myth 5: When starting with a battery in winter, using the starter continuously can cause damage to the battery due to excessive discharge.
