  • Why won’t my Envoy battery hold a charge? A car battery that needs to be jump-started every time is as good as dead. It may be getting old.

Stop in for a free battery check at your favorite Firestone Complete Auto Care and get a handle on your car battery’s health.

  • How much will replacing my GMC Envoy’s battery cost if I get a DieHard battery? You can find affordable Envoy batteries by using one of our car battery coupons, when available. Plus, every DieHard battery comes with extra coverage thanks to DieHard Assurance and a free replacement warranty.
  • How long is a car battery good for? 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 stuff around my Envoy’s battery post? A chemical reaction between battery acid and the air can cause a white, crusty buildup to form on the terminals of your Envoy car battery. This buildup — known as corrosion — can impede the flow of electricity and cause a range of issues, from poor performance to premature battery failure.
  • How do I remove corrosion from my Envoy car battery? Regularly inspecting and cleaning your battery terminals will help keep your Envoy’s electrical system running smoothly. Before cleaning, reference your owner’s manual for instructions on how to disconnect the battery cables. Once the cables have been disconnected, gently clean the terminals with a mixture of water and baking soda, a wire brush, and a rag.
