  • Why won'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 in for a free battery check at your favorite Firestone Complete Auto Care and get a handle on your car battery’s health.
  • What happens to my old RX350 battery? We recycle it, taking care of both your car and the Earth.

  • What is the average lifespan of a car battery? 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.
  • What is the white, crusty stuff around my RX350’s battery post? The white, crusty stuff that can accumulate around RX350 car battery terminals is called corrosion. It is caused by a chemical reaction between the battery acid and the air, which creates a white, powdery substance that can build up on the terminals over time. Corrosion can interfere with the flow of electricity between the battery post and the car's electrical system, sometimes leading to poor electrical performance, difficulty starting, and even premature battery failure.
  •  How do I clean corrosion off my RX350 vehicle 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.
