Do Not Replace Your Car Battery Early: It Is A Waste

Walk into any auto parts store or service center, and you will hear the same advice. "Your battery is two years old. You should replace it before winter. It"s cheap insurance against being stranded." This advice is delivered with such confidence that millions of drivers follow it without question. Every two years, or sometimes every three years, they spend one hundred to two hundred dollars on a new battery, recycling the old one before it has failed. The logic seems sound. A dead battery always fails at the worst possible moment. Replacing it early prevents that moment. This logic is flawed. Early replacement does not prevent failure. It guarantees waste.
