  • Why won't my RX battery stay charged? A battery is in its final hour when it will no longer hold a charge. The battery might be old. Or, you’ve been leaving the doors slightly open and the lights on overnight. Stop by for a free battery test at your local Firestone Complete Auto Care and get a handle on your car battery’s health.
  • What happens to my old RX battery? We recycle it! Nearly 100% of all lead-acid batteries are recyclable.

  • How long can I expect my car battery to 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 RX’s battery post? The white, crusty stuff that can accumulate around RX 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 a corroded RX battery terminal? Regularly inspect the terminals and clean them with a mixture of baking soda and water, a wire brush, and a rag. Disconnect the battery cables before cleaning to help avoid the risk of electrical shock. Always reference and follow the instructions in your vehicle owner’s manual prior to disconnecting the battery cables.
