  • How long is a car battery good for? 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 RX-7’s battery post? If you notice white, crusty stuff around the battery terminals of your RX-7, 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 RX-7’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.
  • What do I do about corrosion on my RX-7 car battery? You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your RX-7 owner's manual to learn how to disconnect the battery cables. After disconnecting the cables, use a mixture of water and baking soda, a wire brush, and a rag to carefully clean the terminals.
