The average battery life of a car is 2 years, and it can be used for more than 3 years if it is well maintained. The length of the battery life of the car is not only

It is only related to structure and quality, and is also inseparable from the usual use and maintenance. Many friends pay attention to appearance when they are setting an example for their car.

There are few checks on the battery, and there are certain misunderstandings in understanding.

    There is no corrosive material on the exterior of the battery pole post, as long as it is not loose. Corrosion appears on the exterior, the inner surface of the terminal

Corrosion will also occur, resulting in an increase in the resistance value, affecting the normal charging and discharging of the battery, and must be handled in time.

    When using a maintenance-free battery, it is simply considered maintenance-free without any maintenance. Maintenance-free can reduce maintenance costs and times

However, it is still essential for the cleaning of the exterior, so that "maintenance-free" is more directed to the inside of the battery.

    When the liquid level is low, replenish the electrolyte or add purified water instead of the distilled water required. If an electrolyte containing sulfuric acid is added, the electricity is stored back.

The concentration of electrolyte inside the pool increases, boiling, acid mist and other phenomena may occur, which seriously affects the service life of the battery; instead of steaming with pure drinking water

Used in distilled water, pure water contains a variety of trace elements, which have adverse effects on the battery.

    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.

phenomenon.

    When the battery is started in winter, the starter is used continuously, causing the battery to be damaged due to excessive discharge.

    In order to prolong the service life of the battery and avoid the occurrence of faults such as anchoring, we should pay attention to the following points in the maintenance of the battery:

    1. Always check the color of the electric eye for maintenance-free batteries. Green is sufficient; black is low and needs to be recharged

Gray or light yellow is insufficient electrolyte. Because the maintenance-free battery cannot be filled, the battery should be replaced immediately.

    2. The battery should be placed securely on the vehicle to prevent the battery connection from falling off due to vibration during driving, resulting in power interruption.

    3. Keep the battery surface clean. If solid oxides are found on the poles, they should be flushed with hot water in time to remove them.

It does not affect the continuity between the pole and the terminal. After cleaning, wipe the surface of the battery clean and apply butter to the pole and terminal.

Ensure that the poles are not oxidized.

    4. Check the height of the electrolyte at least once a month. For batteries without marking lines, the electrolyte can be added to the high-polar plate 10-15mm;

For two red line batteries, the electrolyte should not exceed the upper red line, otherwise the electrolyte may overflow and form a self-discharge between the positive and negative electrodes, causing the engine to start.

The machine is not easy to start and shortens the battery life.

    5. Adjust the concentration of the electrolyte according to the region and season. In our northeast winter, the concentration of electrolyte should reach 1.28 g / m.

Rise.

    6, the car that is not used for a long time should start the car every one month or so, run at medium speed for about 20 minutes, otherwise it will take too long

Long, the car will not start when the car is in use.

    7. The total length of time for each car is not more than 5 seconds, and the interval between restarts is not less than 15 seconds. In case of multiple starts still not in the car

The reason should be found from other aspects such as circuit, ignition coil or oil circuit. After the fault is removed, the engine will be started, otherwise the battery will be over-discharged.
