When starting the car, uninterrupted use of the starter will cause the battery to be damaged due to excessive discharge. The correct way to use it is that the total time for each start of the car should not exceed 5 seconds, and the interval between restarts should not be less than 15 seconds. In the case that the car cannot be started after multiple starts, the reason should be found from other aspects such as the circuit, the ignition coil or the oil circuit. If the battery cannot be started due to wrong operation or long-term idleness, the battery should be replaced in time to save the battery, or the car should be started by wire borrowing.

　　Be sure to turn off the engine before borrowing power. Pay attention to compare the parameters of the two batteries to see if the specifications are close. After confirmation, connect the battery of the opponent's car and the battery of your own car in parallel, that is, the negative electrode to the negative electrode and the positive electrode to the positive electrode. After the connection is completed, you can start the car. Don't rush to turn off the engine after you start the car. Remove the wiring first. Then let the car run for a period of time, it is best to be able to test drive for a period of time, to charge some auto batteries. If you are not in a hurry, you can park the car in a safe place, where there is a backup power supply, check whether the auto batteries are malfunctioning, and pay attention to timely replacement.

　　And if there is no other car around, if the driving vehicle is in manual transmission, you can put the car in the state of the car, put the car in 1 or 2 gear, the cart will start the car for self-rescue, after the self-rescue is successful, also pay attention to charging the battery and check the damage. If it is an automatic car, then pick up your mobile phone and call for help!
