Why won’t my Caballero battery hold a charge?

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 by for a free battery test at your nearest Firestone Complete Auto Care and get a handle on your car battery’s health.

What happens to my old Caballero battery?

How much do DieHard batteries cost for your GMC Caballero?

You can find affordable Caballero batteries by using one of our car battery coupons, when available. Plus, every DieHard battery comes with extra coverage thanks to DieHard Assurance and a free replacement warranty.

How long can I expect my car battery to last?

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 Caballero’s battery post?

The white, flaky stuff that can build up around your Caballero’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 Caballero, 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 remove corrosion from my Caballero 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 Caballero owner’s manual for instructions on how to do so.
