Why won’t my 6 battery hold a charge?

A battery that won't hold a charge is almost as good as dead. The battery might be old. Or, you’ve been leaving the doors slightly open and the dome lights on during the night. Stop in for a free battery check at your local Firestone Complete Auto Care and get a handle on your car battery’s health.

What’s the cost of DieHard batteries for Mazda 6s?

Mazda 6 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.

What is the white, crusty stuff around my 6’s battery post?

The white, flaky stuff that can build up around your 6’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 6, 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 remove corrosion from my 6 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.
