  • Why won’t my Sierra 2500 battery hold a charge? A car battery that needs to be jump-started every time is as good as dead. The battery may be too 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 to learn more about the state of your battery.
  • What do you do with my dead Sierra 2500 battery? We recycle it, taking care of both your car and the Earth.

  • How long can I expect my car battery to last? A car battery normally lasts three to five years, but this number can vary based on battery type, your driving habits, and battery maintenance.
  • Why is there white, flaky stuff around my Sierra 2500’s battery post? The white, flaky stuff that can build up around your Sierra 2500’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 Sierra 2500, 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 clean corrosion off my Sierra 2500 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 Sierra 2500 owner’s manual for instructions on how to do so.
