What is the average lifespan of a car battery?

Car battery lifespan varies depending on a few factors, including driving conditions, accessories, how well it’s maintained, and the type of battery. On average, a car battery lasts about three to five years.

Why is there white, crusty buildup on my LeSabre’s battery post?

If you notice white, crusty stuff around the battery terminals of your LeSabre, it's likely corrosion. A chemical reaction between battery acid and the air can create a white, powdery substance that builds up over time on the terminals. This buildup can interfere with the electrical connection between the battery and your LeSabre’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I clean a corroded LeSabre battery terminal?

To help extend the life of your battery, you should routinely inspect and clean the terminals using a baking soda and water mix, wire brush, and rag. Be sure to disconnect the battery cables before cleaning and check your LeSabre owner’s manual for instructions on how to do so.
