【Car owner's car knowledge】After get off work in the evening, Ms. Sun prepared to drive home as usual. But when I started, I found that the car couldn't catch fire, and I heard the sound of babbling when it was started. Ms. Sun quickly called the rescue of the 4S store, 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 of power?
I believe that friends who drive often 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 of power, the best way is to pay more attention to the "SOS signal" issued 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 silent. If the above problem occurs, the owner should check whether it is a battery problem.
In order to minimize the power consumption of the battery, experts from the 4S shop make two suggestions: first, avoid turning on the lights or listening to the radio for a long time when the engine is off; second, even if the engine is running, if the parking time is long, you should Turn off the power of unnecessary electrical equipment (inside and outside lights, audio, navigation, etc.). By developing good car habits, you can avoid unnecessary predicaments.
But in case the battery suddenly runs out of power, there are several ways to "self-rescue".
one,Pushing a car to start is the most familiar and effective emergency starting method, but it is a last resort and cannot be used often, because it will damage the engine and clutch to a certain extent. Especially for automatic transmission vehicles, this method should be avoided. .
two,In order to avoid charging when the battery is dead, the car owner should prepare a jumper cable in the car, which can be bought in general auto parts stores. However, when connecting jumper cables, it is important not to get the jumper cables connected in the wrong order. Connect the positive terminal of the dead battery to the positive terminal of the rescue vehicle battery first, and then connect the negative terminal of the rescue vehicle battery to the metal part (ground wire) in the engine room of the dead vehicle. After the jumper cable is connected, the engine of the rescue vehicle can be started, and the speed of the engine can be slightly increased. After about 5 minutes, the dead battery can be charged in an emergency. When charging is complete, jumper cables should be removed in the reverse order of connecting them.
three,The most reliable way is to contact the rescue vehicle in time, then connect the jumper cable and temporarily charge it through the rescue vehicle to start the engine.
Finally, experts remind that the battery life is generally 2 to 3 years. After this period, the car owner pays special attention to the maintenance of the battery at ordinary times, and replaces it in time when necessary to avoid danger.
