  • Why doesn’t my RS5 battery stay charged? A car battery that needs to be jump-started every time is as good as dead. It may be getting old. Or, you may have been leaving your car doors ajar and the lights on overnight. Stop in for a free battery check at your nearest Firestone Complete Auto Care and get a handle on your car battery’s health.
  • What do you do with my dead RS5 battery? We’ll recycle your car battery for you!
  • How much will replacing my Audi RS5’s battery cost if I get a DieHard battery? Audi RS5 batteries can be affordable, especially when there's an available battery coupon. The best part is every DieHard battery comes with a free replacement warranty and extra coverage with DieHard Assurance.
  • What is the average lifespan of a car battery? 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 substance accumulating on my RS5’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 RS5 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 a corroded RS5 battery terminal? 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 RS5 owner’s manual for instructions on how to do so.
