  • How often should I replace my 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 CLS450’s battery post? The white, crusty stuff that can accumulate around CLS450 car battery terminals is called corrosion. It is caused by a chemical reaction between the battery acid and the air, which creates a white, powdery substance that can build up on the terminals over time. Corrosion can interfere with the flow of electricity between the battery post and the car's electrical system, sometimes leading to poor electrical performance, difficulty starting, and even premature battery failure.
  • How do I remove corrosion from my CLS450 car battery? Regularly inspecting and cleaning your battery terminals will help keep your CLS450’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.
