Commonly Asked RX350 Battery Questions

Firestone Complete Auto Care has answers to your top car battery questions. If you have a RX350-specific battery question, pay us a visit. Our technicians have the answers.

  • Why doesn’t my RX350 battery stay charged? A battery is in its final hour when it will no longer hold a charge. It may be getting old. Or, you may have been leaving your car doors ajar and the dome lights on during the night. Stop by for a free battery test at your nearest Firestone Complete Auto Care and get a handle on your car battery’s health.
  • What do you do with my dead RX350 battery? We recycle it, taking care of both your car and the Earth.
  •  How much do DieHard batteries cost for your Lexus RX350? Lexus RX350 batteries can be affordable, especially when there's an available battery coupon. The best part is every DieHard battery comes with a free replacement warranty and extra coverage with DieHard Assurance.
  •  How long do car batteries last? The typical 12-volt car battery may last three to five years, depending on the type of battery, the driving conditions, and how well the battery is maintained.
  • Why is there white, flaky stuff around my RX350’s battery post? The white, flaky stuff that can build up around your RX350’s battery terminals is known as corrosion. Acid leaking from your vehicle’s battery post can have a chemical reaction with the air, leading to an accumulation of the white, powdery substance over time. Corrosion can affect the flow of electricity between your battery and the electrical system in your RX350, possibly causing issues with electrical performance and starting. If left unaddressed for long enough, it may even cause your battery to prematurely fail.
  • What do I do about corrosion on my RX350 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. Be sure to disconnect the battery cables before cleaning and check your RX350 owner’s manual for instructions on how to do so.
