Does the Car Battery Need Replacement?
2 Answers
Batteries that fail inspection need replacement, while those that pass do not. Generally, a car battery can last at least 3 to 5 years before requiring replacement. Regular Battery Inspection: The vehicle's user manual provides clear maintenance recommendations for the battery. If the car is used frequently, the battery should be inspected every two years; if used infrequently, an annual inspection is sufficient. Batteries that fail inspection need replacement, while those that pass do not. Impact of Usage Habits on Battery Lifespan: If the battery is frequently in a low-charge state or if the vehicle's electrical system is equipped with high-power-consuming devices, the battery's lifespan will be shortened accordingly. The battery's longevity is also influenced by the driver's habits, such as frequently making short trips where the vehicle is driven less than 10 kilometers after starting, which can reduce the battery's service life.
As a frequent driver, I always check a few key points before driving to determine if the battery needs replacement. If the engine starts more sluggishly than usual, like a slow-moving old man, or if the warning lights on the dashboard keep flashing, it's time to be alert. Cold starts in winter are particularly challenging, as the battery might fail completely. Last time I checked the voltage, a fully charged battery should read around 12.6 volts—anything below 12 volts is a warning sign. Don’t forget routine maintenance; regularly inspect the battery terminals for white powdery corrosion, and a simple cleaning can extend its lifespan. Batteries typically begin to degrade after about two years, especially with frequent short trips, as insufficient charging accelerates aging. I recommend buying a multimeter to check the voltage yourself—it’s cost-effective and gives peace of mind. Don’t wait until you’re stranded on the roadside to regret it; by then, you’ll need a tow truck, which costs much more.
