How to prevent sudden power failure of the battery?

I believe that friends who often drive will occasionally encounter the situation that the car battery suddenly runs out. 4S shop maintenance staff said that in order to prevent sudden battery power failure, usually the best way is to pay attention to the distress signal in your car. This signal has the following manifestations: first, the transmitter does not turn or turns weakly, so that the transmitter cannot be started; second, the headlights are darker than usual; third, the speaker volume is low, or even not loud. If the above problems occur, the car owner must check whether the battery is defective. In order to minimize the power consumption of the battery, the experts of the 4S shop have put forward two suggestions: first, prevent prolonged turning on the lights or listening to the radio in the case of engine failure; second, even if the engine is running, if If you park for a long time, you should also use electrical equipment (lighting, audio, navigation, etc. inside and outside the car) to cut off power unnecessarily. Develop good car use habits to prevent unnecessary difficulties. But if the battery suddenly runs out, there are several ways to save yourself. The shopping cart is the most familiar and most effective emergency starting method at first, but it is a necessary method and can not be used frequently because it has certain damage to the engine and clutch, automatic transmission vehicles, especially to prevent the use of this method. 2. In order to prevent the battery from being unable to charge when the power is cut off, the car owner should prepare a jumper cable in the car, which can be purchased at general auto parts stores. However, when connecting jumper cables, do not make a mistake in the connection sequence of jumper cables. First connect the positive electrode of the exhausted battery to the positive electrode of the rescue vehicle battery, and then connect the negative electrode of the rescue vehicle battery to the metal part of the engine compartment of the car, without electricity (grounding). After the jumper cable is connected, the rescue vehicle engine can be started, and the engine speed can be slightly increased. After about 5 minutes, the battery can be charged in an emergency without electricity. After charging is complete, remove the jumper cable in the reverse order of connecting the jumper cable. The most reliable method is to contact the rescue vehicle in time, then connect the jumper cable, temporarily charge the rescue vehicle, and start the engine. Finally, experts remind 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, and replace it when necessary or in time to avoid danger.
