How often does the car battery need to be replaced?

The normal service life of a car battery ranges from 1 to 8 years. There is no specific fixed number to use for several years. This has a lot to do with the condition of the vehicle. It can basically be used for more than 3 years when the vehicle generator is normal and the electrical appliances have no leakage and grounding.

It can basically be used for more than 3 years when the vehicle generator is normal and the electrical appliances have no leakage and grounding. If you feel that the battery cannot be charged or the starter is weak, and the headlights are obviously dimmed, you need to remove the battery and charge it with a charger for 12-24 hours. If it still fails and the mileage has reached more than 50,000 km, and the generator is not malfunctioning , You need to consider changing the battery.

The internal resistance of some batteries becomes very large when they are worn out. Once they are charged and discharged, it is normal to measure their no-load voltage with a three-meter. Therefore, it is not possible to measure the no-load voltage alone, but also to measure its discharge current. It is normal that the voltage is not less than 10V during discharge, and it is less than 10V that the battery may be broken and must be replaced. How often does the car battery need to be replaced?

Car maintenance:

1. The car battery should be charged frequently, and the battery will slowly discharge by itself until it is scrapped if it is not used for a long time. Therefore, every interval The car should be started once in time to charge the battery.

2. It is forbidden to use automobile electrical appliances after the car is turned off. Using the battery alone when the engine is not generating electricity will cause damage to it.

3. Do maintenance once every 15000km or 12 months. The maintenance includes changing the oil and the oil grid.

4. It is recommended to change the oil and the oil grid for the first 3000 kilometers.

5. The air filter element and spark plug must be replaced during regular maintenance every 30,000 kilometers.

After using for more than 2 years, the capacity and discharge capacity of car batteries will decrease. The life of a general car battery will not exceed 4 years. Of course, a well-maintained battery will last longer. Let's take a look at the maintenance methods of water-filled lead-acid batteries and maintenance-free lead-acid batteries.

Maintenance-free lead-acid battery

Pay attention to: check the magic eye regularly and keep the battery full.

Because the maintenance-free battery does not have a water filling hole and a battery level scale. We need to judge the state of the battery through the 'magic eye' on the battery. The magic eye is green to indicate that the battery is normal and fully charged; the magic eye is black to indicate that it needs to be charged; the magic eye is white to indicate that the battery needs to be replaced.

In addition, we generally use a voltmeter to check the battery voltage. Although we can detect the voltage value of the battery, we cannot check the load capacity of the battery. In order to check the actual condition of the battery, we should use a dedicated battery tester to check the battery's discharge capacity and load capacity.
