What is the reason for the different service life of the same car battery?

Many car owners think that the quality of the battery is the problem. In fact, it is not all the quality of the battery. A large part of the reason is the problem of the use of the vehicle. Generally, the normal service life of car batteries is about 3 years, but vehicle usage habits and improper maintenance will shorten the battery life. 1. Do not turn on the air conditioner at idle for a long time. When turning on the air conditioner at idle speed, the heat dissipation system and exhaust system driven by the motor will consume a lot of electric energy. If the speed is insufficient, the power generation is usually difficult to meet the power consumption of various electrical appliances. At this time, it is necessary to borrow power from the battery, and the battery power will slowly decrease. Over time, it will inevitably cause a loss of power to the battery. 2. It is a common problem for many drivers to turn off the air-conditioning and audio before turning off. The air-conditioning system and audio system are not turned off after the car is lent to others. The air-conditioning system and audio system will be used next time you drive. It works automatically. At this time, the instantaneous power load of the vehicle is too high when the ignition is straight. As time passes, the battery loses power faster and faster, accelerating the scrapping. In addition, the car is turned off to listen to music. If the battery performance itself is not good, there may not be enough power to support the engine start after half an hour. 3. Remember to close all on-board electrical appliances after parking. Many car owners forget to turn off the lights, especially the headlights, which are high-power and high-current, and the battery may not be able to carry them within a few hours. In the end, they will have to call rescue if they can't hit the car. In addition, some models are set to power the cigarette lighter even 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 devices, they will quickly consume the battery power reserve. , The battery is a big test. When installing electrical appliances, you must consider the battery's endurance. Under normal circumstances, the original circuit on the car does not leave many connection points for the user. The most common one is the cigarette lighter. The standard on-board electrical appliances of the original car match the capacity and model of the battery. If the owner installs some electrical appliances that were not available before, such as a subwoofer, it will cause excessive use of the battery. If the battery on the car has been used for a long period of time, it is not recommended to install on-board electrical appliances in the car. 4. When using the all-weather driving recorder, beware of not driving for a long time. The driving recorder usually has three connection methods: the car automatically turns on, the first gear automatically turns on, and the 24-hour all-weather recording. Especially the 24-hour recording of the driving recorder is to damage the battery life. For the price, it’s okay for the vehicle to start every day. If you forget to turn off the dash cam and start the car a few days later, the battery may be out of order. As long as you don’t drive for 2-3 days, the dash cam will charge the battery. It is reduced to weak ignition and even power consumption, causing irreversible damage to the battery, and thus having to replace the battery with a new one. 6. Frequent start-up damages. Frequent start-up of the vehicle is not a good habit. Frequent start-up of the vehicle under very traffic jams will cause great damage to the battery, because every time the vehicle is started, a large amount of electric energy will be consumed. If the engine is turned off and restarted, the engine will consume a wave of electrical energy after it has not replenished enough power. Over time, the battery will lose power and its life will be reduced. Vehicles equipped with an automatic start-stop system propose to use automatic start-stop, which can reduce the damage to the battery.
