Why won't my Quattro 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’ve been leaving the doors slightly open and the dome lights on during the night. Stop in for a free battery check at your favorite Firestone Complete Auto Care and get a handle on your car battery’s health.

What do you do with my old Quattro battery?

What’s the cost of DieHard batteries for Audi Quattros?

Audi Quattro 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 often should I replace my 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.

Why is there white, crusty buildup on my Quattro’s battery post?

The white, crusty stuff that can accumulate around Quattro car battery terminals is called corrosion. It is caused by a chemical reaction between the battery acid and the air, which creates a white, powdery substance that can build up on the terminals over time. Corrosion can interfere with the flow of electricity between the battery post and the car's electrical system, sometimes leading to poor electrical performance, difficulty starting, and even premature battery failure.

How do I clean corrosion off my Quattro vehicle battery?

Regularly inspect the terminals and clean them with a mixture of baking soda and water, a wire brush, and a rag. Disconnect the battery cables before cleaning to help avoid the risk of electrical shock. Always reference and follow the instructions in your vehicle owner’s manual prior to disconnecting the battery cables.
