What are the signs before car battery failure

Generally speaking, the life of a car battery is 3 to 5 years. Of course, the detailed usage time is also determined according to your driving habits. Moreover, in the process of daily car maintenance, the maintenance and inspection of car batteries are essential. Many car owners have not been driving the new car for a long time, and the car battery is already in a state of depletion. Therefore, our car owners must pay attention to the maintenance of the car battery in the daily use process, and must also know the precursors of the car battery failure. Most car owners have happened before these three kinds of signs before car batteries fail, but they still haven't taken care of them. 1. The indicator light of the car battery is on or bulging occurs. This is the most common sign, and it is also the most intuitive sign. When the car battery failure indicator on the car dashboard lights up, we car owners must pay attention to it. As long as the fault light is on, it means that the car battery has failed, or you find that the car battery is bulging. Generally speaking, there are two reasons for the bulging of the battery. The first is long-term charging, and the second is the exhaust of the battery. The hole is blocked, these are the faults of the battery. At this time, you must drive the car to the repair shop for repair. If you want to replace it, you must replace it in time to avoid accidents in the future driving process. 2. The lights of the headlights are dimmed. Everyone knows that the power supply for the headlights, brake lights and audio equipment on the car comes from the car's battery. If we find that the lights of the car's headlights have become very dim, or that the lights of the brake lights are very weak when braking, it means that your car's battery is about to fail. When idling, the charging power of the car drops, causing the battery to be unable to supply the corresponding voltage, which causes the lights to dim. 3. Difficulty in starting the car Difficulty in starting the car is also one of the most important manifestations of car battery failure. If the car owner can start the car normally but suddenly finds that the car is difficult to start, then the car’s battery has a problem. It is possible that the car is almost scrapped, and the car can no longer be supplied with power. At this time, car owners must replace the battery, otherwise the car will not be able to drive normally.
