I believe that friends who drive often will occasionally encounter problems with sudden battery failure. To prevent the battery from suddenly losing power, the best way 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. If the car encounters a sudden loss of power in the battery, what are the ways to "self-rescue"? First, the start of the cart is the most familiar and most effective emergency start 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, automatic vehicles must avoid using this. The method starts. Second, in order to avoid the battery can not be charged when the power 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. 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. Third, 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. The life of a car battery 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.
