Do car batteries need to be replaced every two or three years? Under what circumstances should car batteries be replaced?

Car batteries, as we all know, are an indispensable part of cars! Many friends will encounter this situation when they go to the 4S shop for maintenance after buying a car for about two years. The 4S shop says that the battery needs to be replaced. How long is the life cycle of the battery? Does it really need to be replaced every two or three years? Let's take a look at the following article for details!

Does a car battery need to be replaced every two or three years?

Not necessarily. It depends on the quality of the battery and your usage habits. Car batteries with automatic start-stop are generally better than ordinary ones, but this is relative. It actually depends on your usage habits. If you often park your car and leave the navigation on, or turn on the audio or watch videos, or use high-power external appliances, the battery will need to be replaced in less than two years. On the other hand, if you have good usage habits, you may be able to extend the life of a battery that was originally only available for three years to four or even five years. For example, you should turn off the air-conditioning system before parking the car (this will avoid damage to the battery when the high current generated when the battery supplies power to the air-conditioning system in addition to the starter the next time you start the car).

When should you replace your car battery?

First, slow start and difficulty in starting. If it is not winter, the low temperature in winter will also cause slow start and difficulty in starting. If this happens when starting the engine in summer, it is likely caused by insufficient battery voltage. You can check whether the voltage is normal.

Second, the car makes a squeaking noise when it starts. This is normal in winter, but in other weather conditions, it still makes a squeaking sound. It is obvious that this is caused by the weakening of the battery's discharge capacity. As long as there is this problem, you can also consider replacing the battery with a new one.

Third, when driving at night, after the car is parked, the headlights are very bright, but when you start to drive away, the headlights will briefly become noticeably dimmer. This situation also indicates that the battery capacity is insufficient and the performance is significantly reduced.

4S shop recommends replacing the battery or not

The 4S shop recommends that you replace the battery to see what the reason is. If the car is still within the warranty period and they tell you that it is free of charge, then replace it. You don't have to pay for it anyway. If they ask you to replace it at their own expense for profit, then you don't have to rush to replace it for now. You can still use it for a while. The biggest phenomenon of a complete battery damage is that the car cannot start or is difficult to start. You can try to start the vehicle. If you feel that the vehicle starts easily, it means the battery can still be used for a while. Just pay more attention when using it (of course, there may be a risk of not being able to start for a while later. Don't worry if you encounter this. Just find a car to help you charge it. At that time, it really needs to be replaced).
