3 meters.
From the query on China.com, we learned that the car's live wire is 3 meters long. It should be noted that the live wire should not be too long. easily lead to an increase in resistance and consume too much energy. The live wire needs to use 16 square meters of copper wire to interconnect the battery electrodes of the two cars. Start the car with power so that the engine idles and the battery loses power. When starting, you must The car remains idle for 15 to 20 minutes while the generator charges the battery.
After lighting the fire once, is it easy to lose electricity? Does it take three to five days to light the fire for half an hour?
The car's live wire is usually about 3 meters long. It should be noted that the live wire should not be too long, this will result in facilly an increase in resistance and excessive energy consumption. .
When the car battery is exhausted, the car is difficult to start. Battery drain will also affect the car's entire power system. In this case you can use boot. the car using the live wire method.
The live wire needs to use 16 square meters of copper wire to interconnect the battery electrodes of the two cars. Start the car with electricity so that the engine idles. the battery is running out of This way the car can start immediately. After starting, the car should remain idling. After 15 to 20 minutes of inactivity, the generator will charge the battery.
In order to avoid significant energy consumption in the car battery, you should develop good driving habits whens you use the car. Before you turn off the car, you need to turn it on. turn off electrical equipment. Car electrical equipment mainly includes car headlights, radios, driving recorders, etc. Some car owners easily forget to turn off the car headlights when driving at night and turn off the engine. money in the car.
It is worth mentioning that the car battery is also affected by temperature. The lower the outside temperature, the lower the power stored in the car battery.
After the vehicle is parked for too long, the battery will lose power, preventing it from starting normally. Most of them will start the vehicle by finding another vehicle to connect power. After starting the vehicle, it should idle or drive for more than 30 minutes. When theengine runs normally, the generator generates electricity and replenishes the battery. When the time reaches a certain duration, the battery can start the vehicle normally, but it is just floating electricity in the battery. Generally, it can only be parked for two to three days. If it exceeds two or three days, the battery is powered. will also be consumed. Therefore, after driving a car, you usually need to restart the car after parking it for two days, idling it, or driving for more than 30 minutes to make sure the battery is replenished. for the next start. If the vehicle is not used all the time, you can remove the negative terminal of the battery when parked again to ensure power to the battery.
