How to deal with the sudden loss of battery power

After work in the evening, Ms. Sun prepares to drive home as usual. But when I started, I found that the car couldn’t catch fire anyhow, and I heard the sound of babble when I started. Ms. Sun hurriedly called the rescue of the 4S shop, and the rescuers told her that the battery was dead. But Ms. Sun had already checked it when she went to work in the morning. The air conditioner and lights were all turned off, and there was no equipment that used electricity. Why did the battery suddenly run out?

I believe that friends who drive a lot will occasionally encounter the same problems as Ms. Sun. The maintenance staff of the 4S shop said that to prevent the battery from suddenly running out, the best way is to pay more attention to the “distress signal” sent by your car. This signal has the following manifestations: First, the starter does not rotate or rotates weakly, so that the starter cannot be started; second, the headlights are darker than usual; third, the volume of the horn is low or even does not sound. When the above problems occur, the car owner should check whether it is a battery problem.

In order to minimize the power consumption of the battery, the experts of the 4S shop put forward two suggestions: First, avoid turning on the lights or listening to the broadcast for a long time when the engine is turned off; second, even if the engine is running, if the parking time is long, you should Turn off the power of unnecessary electrical equipment (lights inside and outside the car, audio, navigation, etc.). Develop good car use habits, you can avoid unnecessary dilemmas.

But in case the battery suddenly runs out of power, there are several ways to “self-help”.

First, cart starting is a *familiar and *effective emergency starting method for everyone, but it is a last resort and cannot be used frequently, because this will cause certain damage to the engine and clutch. Automatic transmission vehicles should especially avoid using this Method starts.

Second, in order to avoid the battery cannot be charged when the battery is dead, the car owner should prepare a jumper cable in the car, which can be purchased in general auto parts stores. However, when connecting jumper cables, you must not make a mistake in the order of connecting jumper cables. First connect the positive terminal of the dead battery to the positive terminal of the rescue car battery, and then connect the negative terminal of the rescue car battery to the metal part (grounding wire) in the engine room of the dead car. After the jumper cable is connected, the engine of the rescue vehicle can be started, and the engine speed can be slightly increased. After about 5 minutes, the dead battery can be charged in an emergency. After charging is complete, remove the jumper cable in the reverse order of connecting the jumper cable.

*The reliable way is to contact the rescue vehicle in time, then connect the jumper cable, and temporarily charge the rescue vehicle to start the engine.

After 　　*, experts reminded that the battery life is generally 2 to 3 years. After this period, the car should pay special attention to the maintenance of the battery in normal times. If necessary, replace it in time to avoid danger.
