The service life of a normal car battery is 2.5 to 3 years. In general, when the car is being maintained, the instructor will help you replace it. Of course, the specific situation still depends on your driving habits. There are not no "battery killers" that lose power in less than two years. What are the signs before the battery fails? ? How much do you know about this problem? ? Today, the editor of Zhengzhou Kanglida Electronic Power Supply Co., Ltd. will give you some information on this issue. I hope it will be helpful to you.

　　 1. The car is more difficult to start than usual: If there are no other factors, if you suddenly find that it is difficult to start your car, it may be a sign that the battery is about to die. Of course, there is another situation in winter, the so-called cold start difficulty in winter. It depends on whether your car is new or it is almost time for the battery to be scrapped.

　　 2. When idling, the headlights turn into "candles": For example, when waiting for a red light or temporarily stopping, you suddenly find that your headlights suddenly dim. This is because when idling, the charging power of the engine drops. If the battery is not powerful at this time and the electric equipment in the car is still being supplied, the power allocated to the headlights outside the car will drop significantly.

　　3. The battery failure warning light is on: there is nothing to say about this, the failure light will remind you directly. You really have to go to the 4S or repair shop to check and replace it.

4. Abnormal noise when starting: due to the weakening of the battery's discharge capacity, the starter squeaks due to poor operation. This situation is particularly obvious at low temperatures, because the battery's activity will decrease when the weather is cold, and this will happen after the weather gets warmer. The situation will improve or disappear, so many car owners don’t care.

5. Observation port change: Many maintenance-free batteries have an observation port. There is a light to indicate whether the battery is working well, green is good, and black is to replace the battery. However, some car owners reflect that this light is not reliable and it is clearly green Can not start the vehicle, just as a reference.

6. Batteries appear to be swollen and leaking: This is mainly to see whether the battery is leaking or swollen. If such a situation occurs, it should be replaced in time. This situation will not only bring about battery life problems, but even Certain safety risks.

7. Voltage changes before and after starting: the normal voltage of the battery is about 12V, and after starting, the voltage will increase to about 13-14V due to the generator charging. Many vehicles have a voltage detection function. Pay attention to the voltage before and after starting to judge the battery life. A good method is that if the vehicle is below 12V when it is not started or below 13V after starting, it should be considered whether there is a problem with the battery.
