Why won’t my CX-30 battery hold a charge?

A battery that won't hold a charge is almost as good as dead. The battery may be too old. Or, you may have been leaving your car doors ajar and the lights on overnight. Stop by for a complimentary battery check at your local Firestone Complete Auto Care and learn more about your battery's charge.

How much will replacing my Mazda CX-30’s battery cost if I get a DieHard battery?

Mazda CX-30 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?

The typical 12-volt car battery may last three to five years, depending on the type of battery, the driving conditions, and how well the battery is maintained.

What is the white, crusty substance accumulating on my CX-30’s battery post?

The white, flaky stuff that can build up around your CX-30’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 CX-30, 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 CX-30 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 CX-30 owner’s manual for instructions on how to do so.
