Why won’t my K30 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 by for a free battery test at your local Firestone Complete Auto Care and learn more about your battery's charge.

What’s the cost of DieHard batteries for Chevrolet K30s?

Chevrolet K30 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 long can I expect my car battery to last?

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.

Why is there white, flaky stuff around my K30’s battery post?

If you notice white, crusty stuff around the battery terminals of your K30, 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 K30’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I clean a corroded K30 battery terminal?

Regularly inspecting and cleaning your battery terminals will help keep your K30’s electrical system running smoothly. Before cleaning, reference your owner’s manual for instructions on how to disconnect the battery cables. Once the cables have been disconnected, gently clean the terminals with a mixture of water and baking soda, a wire brush, and a rag.
