According to battery.com.cn, I believe that friends who drive often will occasionally encounter the start-up and find out how the car can't catch fire. However, when the parking has been checked, the air conditioner and the lights are all turned off. If there is no electricity, how can the battery suddenly lose power?
The maintenance staff of the 4S shop said that the best way to prevent the battery from suddenly losing power is to pay more attention to the "help signal" issued by your car. This kind of signal has the following manifestations: First, the starter does not turn or the rotation is weak, so that the starter can't start; the second is that the headlights are darker than usual; the third is that the speaker volume is small or not. When the above problem occurs, the owner must check if it is a battery problem.
In order to minimize the power consumption of the battery, 4S shop experts put forward two suggestions: First, avoid turning on the lights or listening to the radio for a long time in the case of engine stall; secondly, even if the engine is running, if the parking time is long, it should Turn off the power of unnecessary electrical equipment (inside and outside lights, audio, navigation, etc.). Develop a good car habit to avoid unnecessary dilemmas.
However, in the event of a sudden loss of power in the battery, there are several ways to "self-help."
First, the start of the cart is the most familiar and most effective emergency starting method, but this is a last resort and cannot be used frequently, because it has certain damage to the engine and the clutch. In particular, the automatic vehicle must avoid using this. The method starts.
Second, in order to avoid the battery can not be charged when the battery is not available, the owner should prepare a jumper cable in the car, which can be bought in the general auto parts store. However, when connecting jumper cables, you must not mistake the connection sequence of the jumper cables. First connect the positive terminal of the battery that is not powered to the positive terminal of the rescue vehicle battery, and then connect the negative terminal of the rescue vehicle battery to the metal part of the engine compartment of the vehicle (grounding wire). 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 battery can be charged urgently. After charging is complete, the jumper cable should be removed in the reverse order of connecting the jumper cables.
The most 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.
Finally, experts warn that the battery life is generally 2 to 3 years. After this period, the car mainly pays special attention to the maintenance of the battery, and if necessary, it is replaced in time to avoid danger.
