The problem is the battery. Think about how many years the battery will be used. If she is more than three years old, she will start to age. Check if the battery is replaced. Battery connector terminals are loose or cannot be charged. The reason for the electricity is to check the battery.
If the vehicle battery is severely discharged, it will take a long time after the call for the battery to start properly. For the sake of safety, it is generally recommended to operate normally for more than half an hour after starting to ensure that the battery has sufficient power. Also, don't just idle it. At idle, the power generated by the generator is relatively low and the charging speed is very slow. If there is still no power after that, you should consider replacing the battery or checking for power issues.arge.
Notes on turning on the car:
1 Connect the positive pole of the two cars to the positive pole and the negative pole to the negative pole. .

3. Listen to the sound when it can't start. If it only sounds "click, click, click", it means the battery is low. If there is still a spinning sound from the motor, this is it. there may be other problems.
4. If it still fails to start after a long time of power on, check whether the battery power of both vehicles is the same and you can choose to change the wire with better conductivity.
