Top ILX Car Battery Questions

Firestone Complete Auto Care has answers to your top car battery questions. If you have a battery question that's unique to your Acura ILX battery, visit your nearest store. Our technicians have the answers.

  • Why won't my ILX battery stay charged? A battery that won't hold a charge is almost as good as dead. It may be getting old. Or, you may have been leaving your car doors ajar and the dome lights on during the night. 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 ILX battery? We recycle it, taking care of both your car and the Earth.
  •  How much do Duralast batteries cost for your Acura ILX? You can find affordable ILX batteries by using one of our car battery coupons, when available.
  • 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.
  • Why is there white, crusty buildup on my ILX’s battery post? The white, crusty stuff that can accumulate around ILX car battery terminals is called corrosion. It is caused by a chemical reaction between the battery acid and the air, which creates a white, powdery substance that can build up on the terminals over time. Corrosion can interfere with the flow of electricity between the battery post and the car's electrical system, sometimes leading to poor electrical performance, difficulty starting, and even premature battery failure.
  • How do I remove corrosion from my ILX car 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.
