Why won't my RDX 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 a habit of leaving your car doors open and the cabin light at night. Stop by for a complimentary battery check at your nearest Firestone Complete Auto Care to learn more about the state of your battery.

What happens to my old RDX battery?

What’s the cost of DieHard batteries for Acura RDXs?

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.

What is the white, crusty substance accumulating on my RDX’s battery post?

The white, flaky stuff that can build up around your RDX’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 RDX, possibly causing issues with electrical performance and starting. If left unaddressed for long enough, it may even cause your battery to prematurely fail.

What do I do about corrosion on my RDX 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.
