Q: What is the average life and cost of a car battery?
A: Car batteries commonly last around 5 years. The battery’s life is dependant on the environment, the car’s charging system, and usage. If your battery is more than 4 years old, get it load tested at an auto repair facility. The load test will indicate if your battery is close to failing. A new battery commonly costs between $100 to $150 and is cheap insurance to keep your car starting even on those cold days.
