What is the service life of a start-stop battery?

[MadelynAnn]

The service life of a start-stop battery is typically around 3-4 years. If it exceeds this period, it is necessary to frequently check the battery's working condition. Methods to determine symptoms of a damaged car battery are as follows: 1. The most noticeable phenomenon is the feedback when starting the car. If you feel that starting the car is quite difficult, it is likely due to battery aging. However, there are many other factors that can cause difficulty in starting, such as severe carbon buildup and abnormal spark plugs, so it is necessary to consider other conditions as well. 2. If, while experiencing difficulty starting the car, the horn is not as loud as before, it is likely because the battery has aged to a certain extent and needs to be replaced promptly. Additionally, the car's headlights may also be affected, resulting in dimmer light. 3. Another symptom is the battery fault light, which is the most intuitive indicator, as this light specifically reflects whether there is an issue with the battery. Therefore, when the battery fault light comes on, it undoubtedly indicates an abnormality, and it is necessary to promptly visit an auto repair shop for inspection. If the issue is due to a damaged battery, a new battery should be replaced.
