How long do car batteries last?

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.

What is the white, crusty stuff around my Z4’s battery post?

If you notice white, crusty stuff around the battery terminals of your Z4, 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 Z4’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I clean corrosion off my Z4 vehicle battery?

Regularly inspecting and cleaning your battery terminals will help keep your Z4’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.
