  • Why doesn’t my S5 battery stay charged? A battery is in its final hour when it will no longer hold a charge. It may be getting old. Or, you’ve been leaving the doors slightly open and the cabin light at night. Stop in for a free battery check at your local Firestone Complete Auto Care and learn more about your battery's charge.
  • What happens to my old S5 battery? We recycle it! Nearly 100% of all lead-acid batteries are recyclable.
  • How much will replacing my Audi S5’s battery cost if I get a DieHard battery? You can find affordable S5 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.
  • What is the average lifespan of a car battery? Car battery lifespan varies depending on a few factors, including driving conditions, accessories,  how well it’s maintained, and the type of battery. On average, a car battery lasts about three to five years.
  • What is the white, crusty stuff around my S5’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 S5 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 S5 vehicle battery? Regularly inspecting and cleaning your battery terminals will help keep your S5’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.
