How much do DieHard batteries cost for your Audi A4?

Audi A4 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 is a car battery good for?

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, crusty buildup on my A4’s battery post?

If you notice white, crusty stuff around the battery terminals of your A4, 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 A4’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I clean corrosion off my A4 vehicle battery?

Regularly inspecting and cleaning your battery terminals will help keep your A4’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.
