Why won’t my G20 battery hold a charge?

A car battery that needs to be jump-started every time is as good as dead. It may be getting old. Or, you’ve been leaving the doors slightly open and the lights on overnight. Stop by for a complimentary battery check at your nearest Firestone Complete Auto Care and get a handle on your car battery’s health.

How much do DieHard batteries cost for your Chevrolet G20?

How long is a car battery good for?

A car battery normally lasts three to five years, but this number can vary based on battery type, your driving habits, and battery maintenance.

Why is there white, crusty buildup on my G20’s battery post?

The white, flaky stuff that can build up around your G20’s battery terminals is known as corrosion. Acid leaking from your vehicle’s battery post can have a chemical reaction with the air, leading to an accumulation of the white, powdery substance over time. Corrosion can affect the flow of electricity between your battery and the electrical system in your G20, possibly causing issues with electrical performance and starting. If left unaddressed for long enough, it may even cause your battery to prematurely fail.

How do I clean corrosion off my G20 vehicle battery?

Regularly inspecting and cleaning your battery terminals will help keep your G20’s electrical system running smoothly. Before cleaning, reference your owner’s manual for instructions on how to disconnect the battery cables. Once the cables have been disconnected, gently clean the terminals with a mixture of water and baking soda, a wire brush, and a rag.
