Answers to Your RSX Car Battery Questions

Firestone Complete Auto Care has answers to your top car battery questions. If you have a RSX-specific battery question, visit your nearest store. Our technicians are happy to help.

  • Why won't my RSX battery stay charged? A battery that won't hold a charge is almost as good as dead. The battery might be old. Or, you may have been leaving your car doors ajar and the lights on overnight. Stop by for a free battery test at your local Firestone Complete Auto Care and get a handle on your car battery’s health.
  • What do you do with my dead RSX battery? We’ll recycle your car battery for you!
  •  How much do DieHard batteries cost for your Acura RSX? You can find affordable RSX 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 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 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.
