How to protect the car battery?

What is the relationship between the air conditioner and the battery? Of course, it does matter. When the air conditioner is turned on at idle speed, the heat dissipation system and exhaust system driven by the motor will consume a lot of electric energy. If you turn on the audio, the driving recorder records, the mobile phone charges, etc., the generator speed is insufficient when the engine is idling. , The power generation is usually difficult to meet the power consumption of various electrical appliances. At this time, it is necessary to borrow from the battery, and the battery power will slowly decrease. After a long time, it will inevitably cause a loss of power to the battery, but whoever is okay will take hours Turn on the air conditioner for unit idling? Of course turning on the air conditioner at idle for a long time is not healthy, is it? In short, it's better to turn on the air conditioner less for a long time. 2. Please drive the car before turning on the stereo. This is actually the same as turning on the air conditioner at idling speed. In order to save fuel and money, many car owners turn on the stereo to listen to music when the car is turned off. If the battery performance itself is not good, it may not be enough after half an hour. The amount of electricity supports the engine to start. The car CD player modified by the author has a voltage display function. When the sound is turned on when the flame is off, it is difficult to start the engine when the voltage drops to 11.5V. Therefore, don’t listen to songs while the engine is turned off. Listening to songs at idle speed is just a slow-down strategy. 3. Turn off the air conditioner before turning off the engine. Turn off the air conditioner and not turn off the air conditioner. It is a common problem for many drivers (especially after the car is lent to someone else, the air conditioner and audio are not turned off), they don’t even realize that they will turn on the key switch next time. (Before ignition) The air-conditioning system and the audio system work automatically. At this time, the ignition directly causes the vehicle's instantaneous power load to be too high. As time passes, the battery loses power faster and faster, and the acceleration is scrapped. 4. After parking, remember to turn off all on-board electrical appliances, use less external power to get off the car and forget to turn off the lights. I think many people have tried it, especially the headlights, which have high power and high current, and the battery may not be able to carry it within a few hours. In the end, if you can't hit the car, you have to call rescue. In addition, the cigarette lighter of some models can still supply power after the key is removed. At this time, if you continue to charge external electrical appliances, use external car vacuum cleaners or air pumps and other relatively high-power equipment, they will quickly consume the battery power reserve. , It is no small test for the battery.
