5-10 minutes. Be careful when turning on the power: the battery is too drained and there will be no electricity left in the battery, causing the device to not turn on. At this point, you just need to increase the throttle of the car that has power, charge the car if it loses power for about 5 minutes, and then start it again.
If the vehicle battery is confirmed to be low, you need to find other vehicles or batteries to save. The front of the rescue vehicle should be as close as possible to the front of the rescued vehicle to avoid being too far away and not having enough cable length.
Master Feng, a maintenance technician with many years of experience, said that when rescuing, it is best to cut off the power of the rescued vehicle first to avoid inadvertently connecting the positive and negative poles of the battery upside down, causing un short circuit in the vehicle circuit and damaging the vehicle electronics, damaging the equipment.
I once heard that some car owners did not turn off the vehicle's power supply and connected the positive and negative poles in reverse, which ultimately caused the system to malfunction vehicle audio. Therefore, it is best to wait until the wires are connected to confirm that they are connected correctly before applying power and starting the vehicle.
Detailed information:
The problem you will encounter is that the battery cable is connected, but it still fails to light the fire and there is no response . There are generally two reasons:
The battery is too drained and there is no electricity left in the battery, which will cause it to be unable to operate.turn on the phone. At this point, you just need to increase the car's throttle with power, charge the car with power loss for a while, about 5 minutes, and then start it again. Because the battery cable is not properly tightened. Because there may be rust on the battery stakes.
As a result, there is poor contact with the battery cable, or there is no direct contact. There's no current flowing through it, and of course it still can't start. The inspection method is to see if there is sparking when connecting the last battery cable clamp. If there are sparks, this proves that the contact is good. If there is no spark, the contact may not be good.

The fire line of a car is generally several meters
Solutions to the problem of a dead car battery: 1. Fire wire: When buying a car, the fire wire is usually given in the safe in case of emergency. If the vehicle is in a community or underground garage, you can ask. the car owner for help so that it can start easily. 2. Car power bank: If you don't have a fire wire, you can prepare a car power bank. A car power bank is different from a cell phone power bank. The current of a car power bank is very high, 10000mA. , and there are special wires to connect the current coming from the car, so that it can help the electric current do the job. Additionally, the price of an external car battery is not very expensive and you can usually buy it for a few hundredes of yuan.
Detailed information:
The car's live wire is usually about 3 meters long. It should not be too long,the resistance will expand and consume electricity. too short, it will not be easy to connect. When the car battery is exhausted, it will damage the vehicle's power and electrical distribution system, preventing the car from starting. If the engine stalls halfway and won't start, calling a rescue vehicle will cost more to tow the vehicle. At that time we can find another car to respond in case of emergency.
Use 16 square meters of copper wire to interconnect the battery levels of the two cars, then start the other car to idle its engine at high speed. Then learn how to start your car in an exploratory manner. If the battery is low, the car should start quickly. After starting and maintaining the starting state for 15-20 minutes, the generator set will finish charging the battery.
Once the battery sees iture exhausted, you should immediately use a battery charger to charge and activate it. If the battery charger cannot be used to charge, you must use the high-strength repair and improvement work of. The recovery tool. It can only be charged when the voltage reaches more than 10V. If the battery voltage is lower than 9V and battery charging and repairing cannot increase the working voltage, the battery needs to be replaced .
Daily attention must be paid to battery maintenance. If the car is to be left for a long time, the battery level wire should be removed to avoid loss of power consumption. 10 days without high-speed train. For long-term parking, the car should be started approximately every five days, keeping the engine idling and allowing the tank generator tomanage the battery.
