How Long Do Car Batteries Last
Car batteries don’t last forever. Most drivers know this, but the actual lifespan often surprises people. On average, a car battery lasts 4 to 6 years, depending on usage, driving conditions, and maintenance habits.
Recently, a car owner shared his real-world experience. His second battery ran for 5 years and 7 months, covering about 30,847 km before it completely gave up. One morning, the car refused to start. The dashboard lights flickered, then went blank. After multiple failed attempts, he knew the battery had reached the end of its life.
