Why won’t my Avalanche battery hold a charge?

A battery that won't hold a charge is almost as good as dead. The battery might be old. Or, you’ve been leaving the doors slightly open and the dome lights on during the night. Stop by for a free battery test at your local Firestone Complete Auto Care to learn more about the state of your battery.

What do you do with my dead Avalanche battery?

We recycle it! Nearly 100% of all lead-acid batteries are recyclable.

How much will replacing my Chevrolet Avalanche’s battery cost if I get a DieHard battery?

Chevrolet Avalanche 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?

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 substance accumulating on my Avalanche’s battery post?

The white, crusty stuff that can accumulate around Avalanche 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 Avalanche 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 Avalanche owner’s manual for instructions on how to do so.
