Why won’t my 98 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’ve been leaving the doors slightly open and the lights on overnight. Stop by for a complimentary battery check at your favorite Firestone Complete Auto Care to learn more about the state of your battery.

How often should I replace my 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 98’s battery post?

The white, crusty stuff that can accumulate around 98 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.

How do I clean corrosion off my 98 vehicle 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.
