  • Why doesn’t my GLS450 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 may have been leaving your car doors ajar and the cabin light at night. Stop by for a complimentary battery check at your nearest Firestone Complete Auto Care and get a handle on your car battery’s health.
  • What happens to my old GLS450 battery? We recycle it, taking care of both your car and the Earth.

Plus, every DieHard battery comes with extra coverage thanks to DieHard Assurance and a free replacement warranty.
  •  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.
  • What is the white, crusty stuff around my GLS450’s battery post? The white, flaky stuff that can build up around your GLS450’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 GLS450, 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 GLS450 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 GLS450 owner’s manual for instructions on how to do so.
