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 may be 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 with the exception of the starter, other electrical devicesElectrics require a 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 that 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.
1. Turn on and start. If the car is unloaded and cannot start, you can find a carwith a 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-powered cart. The car will not start without electricity. If there are enough people around and willing to help, you can find more people to push the car and use human power to turn the engineand 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.
