Why won’t my RX-8 battery hold a charge?

A car battery that needs to be jump-started every time is as good as dead. The battery may be too old. Or, you may have a habit of leaving your car doors open and the lights on overnight. Stop by for a free battery test at your local Firestone Complete Auto Care to learn more about the state of your battery.

What do you do with my dead RX-8 battery?

We recycle it! Nearly 100% of all lead-acid batteries are recyclable.

How much do DieHard batteries cost for your Mazda RX-8?

You can find affordable RX-8 batteries by using one of our car battery coupons, when available. Plus, every DieHard battery comes with extra coverage thanks to DieHard Assurance and a free replacement warranty.

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 RX-8’s battery post?

If you notice white, crusty stuff around the battery terminals of your RX-8, it's likely corrosion. A chemical reaction between battery acid and the air can create a white, powdery substance that builds up over time on the terminals. This buildup can interfere with the electrical connection between the battery and your RX-8’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I clean a corroded RX-8 battery terminal?

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.
