  • What do you do with my dead NSX battery? We recycle it, taking care of both your car and the Earth.
  •  How much do DieHard batteries cost for your Acura NSX? Acura NSX 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 often should I replace my 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.
  • Why is there white, flaky stuff around my NSX’s battery post? The white, flaky stuff that can build up around your NSX’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 NSX, 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 a corroded NSX 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 NSX owner’s manual for instructions on how to do so.
