Does a car battery need to be replaced after 6 years of use?

[DallasLee]

There is no fixed replacement cycle for car batteries. If the battery's charging performance is poor, it is recommended to replace it. Factors affecting battery lifespan: Frequently modifying car circuits, adding high-power headlights, installing high-power dash cams, one-touch window lifters, and other devices; poor driving habits, such as many drivers enjoying listening to music while driving or turning on the radio and music devices without starting the car; prolonged car inactivity, as leaving the car unused for long periods can also cause battery deterioration, as various electronic devices in the car remain connected to the battery, leading to current drainage over time. How to maintain a car battery: Minimize modifications to car circuits and the installation of various electronic devices, as current overload can lead to excessive battery wear and ultimately affect its lifespan; prevent the car battery from self-discharging by remembering to turn off all electronic devices before shutting off the engine; start the car regularly.
