The life of a battery is generally 1 to 2 years. If the user installs some appliances that were not originally available, such as a subwoofer, it may cause excessive use of the battery. In the maintenance of the car, the maintenance of the battery is also very important. If you develop bad habits, it will shorten the service life of the battery or cause damage. If used well, the battery can be used for 2 to 3 years. However, if the use is unreasonable, it may be replaced in about half a year. Nowadays, there are more and more electric devices on the car. Therefore, when using these electric devices, the owner should try not to overload the battery. Taking electric windows and skylights as an example, the owner should complete its lifting and closing before the engine is turned off, because if the engine is turned off, it will stop generating electricity. At this time, lifting the window will increase the load of the battery, which will easily cause the battery. damage. The same is true for the lights. If there is no special need to turn off the fire, the headlights should be turned off first, then the fire should be turned off. When starting the car at night, the headlights should be turned on and then turned on to minimize damage to the battery. If the battery is operated while the engine is stopped, it is necessary to prevent the battery from losing power, because if the power loss is likely to cause damage to the battery, if the power loss is serious, the battery will be scrapped in advance.
