Commonly Asked RX400h Battery Questions

Get answers to common car battery questions, from Firestone Complete Auto Care. If you have a RX400h-specific battery question, pay us a visit. Our expert techs have the answers you need.

  • Why won't my RX400h battery stay charged? A battery that won't hold a charge is almost as good as dead. The battery may be too old. Or, you’ve been leaving the doors slightly open and the lights on overnight. Stop in for a free battery check at your local Firestone Complete Auto Care to learn more about the state of your battery.
  • What do you do with my old RX400h battery? We recycle it! Nearly 100% of all lead-acid batteries are recyclable.
  •  How much do DieHard batteries cost for your Lexus RX400h? You can find affordable RX400h batteries by using one of our car battery coupons, when available. Plus, every DieHard battery comes with extra coverage thanks to DieHard Assurance and a free replacement warranty.
  • How long can I expect my car battery to last? You can usually get three to five years out of your car battery. However, battery type, how well you maintain your battery, and your driving habits can all affect your battery’s lifespan.
  • Why is there white, flaky 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 clean corrosion off my RX400h vehicle battery? Regularly inspecting and cleaning your battery terminals will help keep your RX400h’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.
