Will turning off the automatic start and stop for a long time hurt the battery?

Auto-start-stop technology is an energy-saving and environmentally friendly feature on modern vehicles, which can automatically turn off the engine when the vehicle is stopped, thereby reducing fuel consumption and emissions. However, many car owners are concerned that turning off the automatic start-stop function for a long time will cause damage to the battery. There is some truth to this concern, but it is not entirely true.

First, let's take a look at how auto-start-stop technology works. When the vehicle is stopped, the engine automatically shuts down, and the battery is responsible for supplying power to the vehicle's electronic devices, such as air conditioning and stereo. When the vehicle needs to be started, the battery provides electricity to the engine to start and recharges it through the generator after the engine starts. As a result, the battery takes on an additional load during the automatic start-stop process.

Turning off the automatic start-stop function for a long time may have a certain impact on the battery. Since the battery needs to be started and stopped frequently, its lifespan may be affected to some extent. In addition, if the owner stops the vehicle for a long time without using the vehicle, the battery may lose power because it has not been charged for a long time. Therefore, it is recommended that car owners can consider turning off the automatic start-stop function or using a special battery maintainer to protect the battery when parking for a long time.

However, not all vehicles will damage the battery due to the automatic start-stop function being turned off for a long time. Modern car batteries usually have a certain charging protection function, which can stop the power supply when the battery is too low to avoid damaging the battery. Therefore, it is only in extreme cases that the battery can be damaged by a prolonged shutdown of the automatic start-stop function.

In summary, turning off the automatic start-stop function for a long time may have a certain impact on the battery, but it will not directly cause damage to the battery. The owner can decide whether to turn off the automatic start-stop function according to the actual situation, or take some measures to protect the battery. In daily use, regularly checking the power and health status of the battery is also one of the important measures to protect the battery.
