Why won't my Eclipse battery stay charged?

A battery that won't hold a charge is almost as good as dead. It may be getting old. Or, you may have a habit of leaving your car doors open and the cabin light at night. Stop in for a free 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?

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 Eclipse’s battery post?

The white, crusty stuff that can accumulate around Eclipse 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 Eclipse 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 Eclipse owner’s manual for instructions on how to do so.
