Why won't my G1500 battery stay charged?

A battery is in its final hour when it will no longer hold a charge. The battery might be old. Or, you may have a habit of leaving your car doors open and the lights on overnight. Stop by for a complimentary battery check at your nearest Firestone Complete Auto Care and learn more about your battery's charge.

What do you do with my dead G1500 battery?

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

What is the average lifespan of a car battery?

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

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.
