Or, you’ve been leaving the doors slightly open and the dome lights on during the night. Stop by for a free battery test at your favorite Firestone Complete Auto Care to learn more about the state of your battery.
  • What do you do with my old RSX battery? We recycle it! Nearly 100% of all lead-acid batteries are recyclable.
  • What’s the cost of DieHard batteries for Acura RSXs? Acura RSX 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.
  • 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 substance accumulating on my RSX’s battery post? The white, flaky stuff that can build up around your RSX’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 RSX, 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 corrosion off my RSX vehicle battery? Regularly inspecting and cleaning your battery terminals will help keep your RSX’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.
