  • 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.
  • Why is there white, flaky 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 clean corrosion off my Envoy 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 Envoy owner’s manual for instructions on how to do so.
