How much do DieHard batteries cost for your Jaguar XJS?

Jaguar XJS 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 do car batteries 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 XJS’s battery post?

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

How do I clean corrosion off my XJS vehicle battery?

To help extend the life of your battery, you should routinely inspect and clean the terminals using a baking soda and water mix, wire brush, and rag. Be sure to disconnect the battery cables before cleaning and check your XJS owner’s manual for instructions on how to do so.
