How long is a car battery good for?

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 DTS’s battery post?

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

How do I clean a corroded DTS battery terminal?

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 DTS owner’s manual for instructions on how to do so.
