Why doesn’t my G1500 battery stay charged?

A battery that won't hold a charge is almost as good as dead. The battery may be too old. Or, you may have a habit of leaving your car doors open and the dome lights on during the night. Stop in for a free battery check at your local Firestone Complete Auto Care to learn more about the state of your battery.

What do you do with my old G1500 battery?

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

What’s the cost of DieHard batteries for GMC G1500s?

GMC G1500 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.

What is the average lifespan of a 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.

What is the white, crusty stuff around my G1500’s battery post?

The white, crusty stuff that can accumulate around G1500 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.

What do I do about corrosion on my G1500 car battery?

You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your G1500 owner's manual to learn how to disconnect the battery cables. After disconnecting the cables, use a mixture of water and baking soda, a wire brush, and a rag to carefully clean the terminals.
