How much do DieHard batteries cost for your Chevrolet Blazer?

Chevrolet Blazer 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?

A car battery normally lasts three to five years, but this number can vary based on battery type, your driving habits, and battery maintenance.

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

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

How do I clean corrosion off my Blazer vehicle battery?

Regularly inspecting and cleaning your battery terminals will help keep your Blazer’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.
