1. Turn on and start. If the car is discharged and cannot start, you can find a car with relatively sufficient battery and start the car by charging it. The method is to connect the positive and negative terminals of the two car batteries, connect the negative and negative terminals of the batteries, and use the energy from someone else's car battery to start the vehicle.
2. Use an external car battery backup. Car emergency power banks can be purchased at 4S stores and online. Normally keep the power bank fully charged. Once the vehicle runs out of power and cannot start, you can use the power bank to start the car.
3. Human cart. The car will not start without electricity. If there are enough people around and willing to help, you can finduve more people to push the car and use human force to turn the engine and start the car. But this starting method is limited to manual transmission cars.
4. Replace the battery with a new one. The car has no power and cannot start, or the battery may be aging and no longer working properly. In this case, you can only go to a 4S workshop or auto repair shop to replace the battery with a new one.
The car battery is dead and cannot start the fire. Should I replace the battery?
The car's battery and generator are used for many electrical jobs. equipment and maintenance services, but if it is found that there is a fault with the electrical equipment when there is no power supply, we can use the following methods to determine whether the battery is broken or ifthe generator is broken.
< p>If the vehicle cannot start under normal circumstances, this proves that it is the battery that is defective or dead. It can be proven that a battery failure can be triggered by energizing the battery. When the engine starts normally but stalls while driving, the generator is broken because the generator cannot work properly and the vehicle automatically shuts down when the battery is exhausted.Symptoms of a broken car alternator include:
1. If the car charging light is still on, it is because the alternator is broken and cannot be charged normally.
2. When battery power is reduced, electrical equipment such as headlights slowly begin to dim;
3. When the internal parts of the generator are damaged, strange sounds are heard; carried out ;
p>
4. VoltageThe battery voltage is lower than 13V-14V after the vehicle is started normally.
Of course, this is just a simple way for us to judge the defect ourselves. If you want a more accurate judgment, it is best to find a professional repair shop or 4S workshop for inspection.
In fact, the generator plays a very important role in supplying electricity and charging the battery of other electrical equipment in the vehicle. Therefore, in order to extend its lifespan, here are some tips for daily maintenance of generators:
1. Regularly clean the dust and dirt on the surface of the generator to maintain good ventilation and heat dissipation; /p>
2. Check regularly whether the generator mounting bolts are loose;
3. Adjust the appropriate belt tension. Too loose or too tight tension will affect the normal working conditional of the generator.
If it is a minor fault in the generator, it can be repaired by replacing the accessories. But if the copper windings of the generator are burned out, it is recommended to replace them. Due to the replacement of a generator cost is not particularly high. If you replace the internal parts, not only will it take time, but a new generator is only a partial part, so it's a bit redundant and a waste of time.
There is no need to replace the battery. There are many reasons for car battery exhaustion, such as insufficient power generation from the generator, body leakage, and private modification of the car. However, it could also be because the car battery is broken. used for a long time. If used for more than three years, the cause of power loss maybe a problem with the battery itself.
The car cannot start, which could be due to various reasons. First, you need to determine if this is due to battery loss. If the car's instruments, headlights and horns are all functioning normally and the only fault is that it does not turn on, we can judge that it is not necessarily the battery that is running out of power.
Because except the starter, other electrical devices require low operating voltage and the starter can only start if it reaches the required voltage. In this case, you must first check if there is a problem with the starter voltage. There is no need to blindly replace the battery.
In the process of ignition when starting the car, only the starter is involved in the work. Therefore, if the starter does not work and the car cannot start, it can be judged thate the starter itself is damaged or the voltage is insufficient. In fact, the probability of the starter being damaged is very small, so this situation can be ignored and the problem focuses on the battery.
If the instrument goes black or hears an abnormal noise when starting, it can be concluded that the battery is running low on power.
