If the car is not driven for a long time, the battery will lose power, much less be able to be recharged.
If the car will not be driven for a long time, it is recommended to start it once a week for 5 minutes. If it is not used for a long time, you can remove the negative terminal of the battery. You can use the following methods to prevent car battery loss:
Turn off all electrical equipment before parking. When the vehicle is parked, do not turn off the engine first. You should turn off USB powered devices, CDs, etc., so that turning off the motor again can protect the battery, otherwise it will accelerate battery consumption. Remember to turn off the lights after turning off the engine. Many Madaha car owners do not look at the dashboard after turning off the engine, leaving the headlightsof the car turned on for a long time. Even small lights will drain the battery if left on during the night. When driving, you should develop a good habit: walk around the car before getting in and out, and then drive away.
2. Avoid driving for long periods and short distances. Some people turn off the car after driving only three to five kilometers. Often, the vehicle battery cannot be fully charged, causing the battery's storage capacity to decrease over time.
3. Don't let the battery run out. The biggest fear of the battery is running out. If this happens, the battery will be seriously injured and become worse. Therefore, you should generally be careful not to turn on the lights or listen to music after turning off the engine.
4. Replace the battery with a good quality batteryuality. When the car battery reaches its age and can no longer be used, it should be replaced with a good quality battery. When purchasing a battery, go to a brand-specific store or a reputable repair shop with a guaranteed warranty. Try not to go to small stores to buy batteries. Many are refurbished and will not last long.
5. Check the battery regularly. If you feel that there is a problem with your vehicle's battery, visit the 4S store regularly to check the battery's energy storage to see if it needs to be replaced. Don't believe the service technician's deception of replacing the battery in advance. Provided you use it carefully, the battery can be used for 3 to 4 years.

You canCharge the car if it's on fire and can't move.
But the principle is to ensure that all electrical devices in the car, except the engine, are turned off. First, as long as the generator is running, the battery can be charged. The power source for the generator comes from the engine. After starting the car, the engine starts working. belt, the battery begins to charge.
It should be noted that charging efficiency is different between idling and driving. When the vehicle is driving, because you need to step on the accelerator, as soon as you step on the accelerator, the engine speed will become faster and the corresponding generator will get more power source.
So at that time the power output of the generator will increase and the battery will be charged more. If it is idling, the generator speed will be slower and the power output will be lower.will be very limited.
However, it is worth remembering that if the car battery is discharged, charging while idling is not recommended. If conditions permit, it is recommended to charge the car while idling. Remove the battery from the car and use the charger to charge it. The battery used in the car has a small capacity, and the battery is mainly used to help the engine start. If the car is not used for a long time, the car battery will automatically discharge and the amount of electricity discharged each day will be reduced. about 1%.
There are generally three phenomena of insufficient power in a car. During the process of starting the car, the starter does not turn or works weakly. After turning on the car headlights, the light appears dim. which indicates that the battery is low. Generally speaking, if the car is notused for half a month, even if the battery still has power, the voltage has been reduced. If the car is not used for a long time, it is recommended to disconnect the negative terminal of the car battery. .
