Why doesn’t my G20 battery stay charged?

A car battery that needs to be jump-started every time is as good as dead. The battery may be too old. Or, you may have been leaving your car doors ajar and the lights on overnight. Stop by for a free battery test at your nearest Firestone Complete Auto Care to learn more about the state of your battery.

What’s the cost of DieHard batteries for Chevrolet G20s?

Chevrolet G20 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?

You can usually get three to five years out of your car battery. However, battery type, how well you maintain your battery, and your driving habits can all affect your battery’s lifespan.

What is the white, crusty stuff around my G20’s battery post?

If you notice white, crusty stuff around the battery terminals of your G20, 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 G20’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

What do I do about corrosion on my G20 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 G20 owner’s manual for instructions on how to do so.
