How Many Years Does the Original Car Battery Generally Last?
3 Answers
The service life of the original car battery is 3 to 4 years, with a mileage of 60,000 to 90,000 kilometers. Details to extend battery life are as follows: Avoid using headlights before starting: Do not turn on headlights or fans before starting the vehicle, nor use power windows, etc. Even at night, wait until the engine is idling before turning on or using these high-power-consuming devices. Check vehicle electronic equipment: Before parking, check whether the power windows have been raised, the headlights have been turned off, the air conditioning has been turned off, the sunroof has been closed, and the fan has been turned off. Perform battery maintenance every six months: If you frequently travel at night, rarely use the car during the day, or only take short trips during the day for several months, it is recommended to have the battery charged for maintenance at an auto repair shop every six months.
I used to find that factory car batteries typically last about three to four years, but sometimes shorter, depending on how you drive. For example, living in a southern city with frequent short commutes can lead to more frequent battery discharge and faster wear. Once, my car battery lasted almost four years before suddenly failing to start—it turned out the battery had completely aged and lost its charge. Paying attention to not leaving lights or the AC on with the engine off can extend its lifespan. Regularly testing the voltage at a repair shop is also important to detect abnormalities early and avoid being stranded. Weather plays a big role too—high temperatures accelerate internal corrosion, reducing lifespan to just over two years. On average, four to five years is common, but each car is different. It’s best to track usage time and replace it promptly to avoid trouble.
As someone who frequently drives in cold areas, the lifespan of the original car battery is indeed quite affected. In winter here, when temperatures drop, the battery tends to have issues and generally lasts only about two to three years. Especially if you feel difficulty starting the car in the morning, it might be nearing the end. I remember once my car battery failed after just two years—fortunately, I checked it in advance and avoided any delays. Maintenance is crucial: keeping the charging system in good condition and minimizing the use of extra power-consuming items like lights and electronics. If you frequently take short trips, the battery may not fully charge, reducing its lifespan to less than three years. It's advisable to have a professional check its condition every autumn; it might last a bit longer once the weather warms up.
