The service life of general automobile batteries is about 2-3 years. If properly used and maintained, it can be used for 4 years. If used and maintained improperly, it will be damaged in advance within a few months. Therefore, it is very important to use automobile batteries correctly.
Generally speaking, the batteries used in cars are replaced once every two years. If well maintained, it can be used for four years. Batteries play an important role in the use of automobiles. If the power supply is not normal, the engine will have problems or stop running. Always check when driving, once a week in summer and once half a month in winter.
At present, there are two kinds of battery life detection, one is with observation hole, which can see green, black and white. Green represents health, black represents charging when the battery is low, and white represents that the battery is almost dead.
Another kind, cigarette lighter charger with voltage display. As soon as the battery is low, the cigarette lighter charger will start flashing. Depending on different models, the battery voltage is lower than 1 1 ~ 10.8V, and the car may not start. Therefore, the health of the battery can also be judged by the voltage of the igniter in the car.
The battery is in good condition. When it is energized, the battery voltage will not drop rapidly. If the battery is in poor condition, the voltage will drop rapidly. Under normal circumstances, the maintenance of cars without automatic start-stop will be slightly better, and it will not be a problem for 5-6 years. The life of a car that starts automatically will be 3-4 years shorter. Therefore, according to the service life, combined with the use situation at that time, it can basically be judged whether the battery is going to hang up.
