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, flaky stuff around my 300’s battery post?

If you notice white, crusty stuff around the battery terminals of your 300, 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 300’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I remove corrosion from my 300 car battery?

Regularly inspecting and cleaning your battery terminals will help keep your 300’s electrical system running smoothly. Before cleaning, reference your owner’s manual for instructions on how to disconnect the battery cables. Once the cables have been disconnected, gently clean the terminals with a mixture of water and baking soda, a wire brush, and a rag.
