Answers to Your GS300 Car Battery Questions

Firestone Complete Auto Care has answers to your top car battery questions. If you have a battery question that's unique to your Lexus GS300 battery, visit your nearest store. Our expert techs have the answers you need.

  • Why won't my GS300 battery stay charged? A car battery that needs to be jump-started every time is as good as dead. The battery might be 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 and get a handle on your car battery’s health.
  • What do you do with my dead GS300 battery? We’ll recycle your car battery for you!
  • How much will replacing my Lexus GS300’s battery cost if I get a DieHard battery? Lexus GS300 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 often should I replace my car battery? A car battery normally lasts three to five years, but this number can vary based on battery type, your driving habits, and battery maintenance.
  • What is the white, crusty substance accumulating on my GS300’s battery post? The white, flaky stuff that can build up around your GS300’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 GS300, possibly causing issues with electrical performance and starting. If left unaddressed for long enough, it may even cause your battery to prematurely fail.
  • How do I remove corrosion from my GS300 car battery? You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your GS300 owner's manual to learn how to disconnect the battery cables. After disconnecting the cables, use a mixture of water and baking soda, a wire brush, and a rag to carefully clean the terminals.
  • Where can I find a battery for my GS300? You can shop for GS300 batteries at your local Firestone Complete Auto Care, and our expert technicians will even handle the installation.
