  • Why won't my Envoy battery stay charged? A battery that won't hold a charge is almost as good as dead. It may be getting old. Or, you’ve been leaving the doors slightly open and the dome lights on during the night. Stop by for a complimentary battery check at your favorite Firestone Complete Auto Care to learn more about the state of your battery.
  • What do you do with my dead Envoy battery? We’ll recycle your car battery for you!
  • What’s the cost of DieHard batteries for GMC Envoys? 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? 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.
  • What is the white, crusty stuff around my Envoy’s battery post? The white, flaky stuff that can build up around your Envoy’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 Envoy, 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 a corroded Envoy battery terminal? You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your Envoy 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.
