Why won't my 6 battery stay charged?

A battery is in its final hour when it will no longer hold a charge. The battery may be too old. Or, you may have a habit of leaving your car doors open and the cabin light at night. Stop by for a complimentary battery check at your local Firestone Complete Auto Care to learn more about the state of your battery.

What is the average lifespan of a car battery?

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.

What is the white, crusty stuff around my 6’s battery post?

If you notice white, crusty stuff around the battery terminals of your 6, 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 6’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I remove corrosion from my 6 car 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 6 owner’s manual for instructions on how to do so.
