  •  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.
  • Why is there white, crusty buildup on my RSX’s battery post? If you notice white, crusty stuff around the battery terminals of your RSX, 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 RSX’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.
  • How do I clean a corroded RSX battery terminal? Regularly inspecting and cleaning your battery terminals will help keep your RSX’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.
