How Long Does a Car Battery Typically Last Before Replacement?

[DelWyatt]

Generally, a car battery needs to be replaced every 3 years. New vehicles typically come with a warranty period of 3 years or over 100,000 kilometers. Beyond this period, car owners should pay special attention to battery maintenance and replace it promptly when necessary to avoid potential hazards. If the battery undergoes frequent power supply cycles, heavy loads, or extensive usage during this time, its lifespan may be shorter. Car batteries require regular maintenance. If you notice poor power supply, avoid using onboard electrical devices such as electric air pumps, audio systems, warning lights, or power windows before starting the car. Additionally, avoid turning off the engine immediately after starting it and then restarting it again.
