  • Why won’t my Tahoe battery hold a charge? A car battery that needs to be jump-started every time is as good as dead. The battery might be old. Or, you may have been leaving your car doors ajar and the dome lights on during the night. Stop by for a complimentary battery check at your local Firestone Complete Auto Care and get a handle on your car battery’s health.

  •  How much do DieHard batteries cost for your Chevrolet Tahoe? Get affordable prices on Chevrolet Tahoe batteries by using one of our limited-time battery deals. Plus, all DieHard car batteries come with a free replacement warranty and extra coverage with DieHard Assurance.
  • What is the average lifespan of a car battery? 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.
  • Why is there white, flaky stuff around my Tahoe’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 Tahoe 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 Tahoe vehicle battery? Regularly inspect the terminals and clean them with a mixture of baking soda and water, a wire brush, and a rag. Disconnect the battery cables before cleaning to help avoid the risk of electrical shock. Always reference and follow the instructions in your vehicle owner’s manual prior to disconnecting the battery cables.
