  • 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.
  • What is the white, crusty stuff around my RX400h’s battery post? A chemical reaction between battery acid and the air can cause a white, crusty buildup to form on the terminals of your RX400h car battery. This buildup — known as corrosion — can impede the flow of electricity and cause a range of issues, from poor performance to premature battery failure.
  • How do I remove corrosion from my RX400h car battery? To help extend the life of your battery, you should routinely inspect and clean the terminals using a baking soda and water mix, wire brush, and rag.
