Top IS350 Car Battery Questions

Firestone Complete Auto Care has answers to your top car battery questions. If you have battery questions that are Lexus IS350-specific, stop by your nearest store. Our expert techs have the answers you need.

  • Why won't my IS350 battery stay charged? A battery is in its final hour when it will no longer hold a charge. The battery may be too old. Or, you’ve been leaving the doors slightly open and the cabin light at night. Stop by for a free battery test at your local Firestone Complete Auto Care to learn more about the state of your battery.
  • What do you do with my dead IS350 battery? We recycle it! Nearly 100% of all lead-acid batteries are recyclable.
  • How much will replacing my Lexus IS350’s battery cost if I get a DieHard battery? Lexus IS350 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.
  • What is the average lifespan of a car battery? 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, crusty buildup on my IS350’s battery post? The white, crusty stuff that can accumulate around IS350 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 remove corrosion from my IS350 car battery? 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.
