Driver should know that, in general, the normal service life of the car battery is 2 to 3 years; However, if the choice is improper or neglectful maintenance, it will lead to premature "lack of power" of the battery and shorten the service life of the product, but in our daily driving, these actions often shorten the service life.
1. The cigarette lighter is in power mode in the flameout state
Cigarette lighter is a part that all cars have, which is used to facilitate the ignition source of cigarette lighting when the owner smokes, and the cigarette lighter is to realize the effect of cigarette lighting through the power supply, which is a very important power output interface of the car. In order to improve the convenience and comfort of the car, many owners often use this power interface to connect a lot of equipment, such as GPS, dashcam, air purifier, etc. These devices rely on cigarette lighter power supply to work. The additional electrical equipment itself increases the burden of the battery, and some models of cigarette lighter in the flame-off state is still in power mode, if you do not unplug the external equipment will consume battery power, loss of battery.
The general use is maintenance-free lead battery, the general service life is about 3 years. However, if used properly, the service life of a battery can even be extended to 5 to 6 years, of course, if used improperly, the battery is likely to be destroyed in less than 3 years. The reason why there is such a big difference and the owner's daily car habits have a lot to do with.
2, do not turn off the multimedia or air conditioning system before extinguishing
Some owners or forget or save time, do not turn off the multimedia system or air conditioning system before the vehicle is turned off, and these systems will automatically open when the vehicle is started next time, which virtually leads to the instantaneous power load of the vehicle is too high, especially the air conditioning is not turned off, which will cause excessive loss of the battery for a long time.
3. Use electricity for a long time after extinguishing
Continuing to use electricity after turning off includes many situations, such as using the electrical appliances in the car for a long time after turning off the engine, and forgetting to turn off the lights and so on. At this time, the car's generator is not working, the battery is in a "dry consumption" state without charging, and the reduction of its electrical capacity is likely to cause the vehicle to fail to start, and excessive discharge has great damage to the battery itself.
4, long or frequent ignition
When starting the engine each time, the ignition time should not exceed 3 seconds, if the first engine fails to start, do not frequently and repeatedly ignite, it should be ignited again after an interval of 15 seconds, otherwise the battery frequently provides a strong current to the starter, causing its own loss.
5. Do not unplug the external device after extinguishing
Now there are more and more external equipment for cars, and the additional electrical equipment itself increases the burden of the battery, and some models of cigarette lighter are still in the power mode in the state of flummox, and the battery is lost.
