How long is the life of a car battery?

About three years, and it can be extended to six years if it is well protected.

The battery life of the original car is 3-4 years, and the mileage is 60,000-90,000 kilometers (depending on the actual use). If you feel that the battery can't be charged or the starting is weak, and the headlights are obviously dimmed, you need to remove the battery and charge it with a charger 12-24 hours. If not, the mileage has reached more than 50,000 kilometers, and the generator is not faulty, so it is necessary to consider replacing the battery.

Car batteries can be divided into two types. One is maintenance-free battery, and the other is common battery.

Ordinary batteries are also called lead-acid batteries. The main advantages of this battery are low price and relatively stable voltage. The shortcomings are also obvious, and it needs regular daily maintenance. It is necessary to check the height of electrolyte regularly and add distilled water.

Matters needing attention

If you want to increase the service life of the battery, you must pay attention to the usual maintenance and care, and don't have the habit of using the car that hurts the battery. When the battery life is about to expire, it is generally felt that the headlights of the car are not as bright as before, or the car will not catch fire when the weather is cold. If a similar situation occurs, it is necessary to check whether it is time to change the battery.

The maintenance method of automobile battery is:

1. Avoid parking your car in the open-air parking lot for a long time to prevent the battery from freezing and damaging.

2. It is not easy to start the engine of a car in winter, and the time for starting the car at a time should not exceed 5 seconds.

3. Charge frequently, and start the car every once in a while to charge the battery.
