Why won’t my Delta 88 battery hold a charge?

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 dome lights on during the night. Stop by for a complimentary battery check at your local Firestone Complete Auto Care to learn more about the state of your battery.

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.

What is the white, crusty substance accumulating on my Delta 88’s battery post?

The white, crusty stuff that can accumulate around Delta 88 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 Delta 88 car battery?

Regularly inspect the terminals and clean them with a mixture of baking soda and water, a wire brush, and a rag. Disconnect the battery cables before cleaning to help avoid the risk of electrical shock. Always reference and follow the instructions in your vehicle owner’s manual prior to disconnecting the battery cables.
