Why doesn’t my WRX battery stay charged?

A battery that won't hold a charge is almost as good as dead. The battery might be old. Or, you’ve been leaving the doors slightly open and the dome lights on during the night. Stop by for a free battery test at your nearest Firestone Complete Auto Care to learn more about the state of your battery.

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.

Why is there white, flaky stuff around my WRX’s battery post?

A chemical reaction between battery acid and the air can cause a white, crusty buildup to form on the terminals of your WRX car battery. This buildup — known as corrosion — can impede the flow of electricity and cause a range of issues, from poor performance to premature battery failure.

How do I remove corrosion from my WRX car battery?

Regularly inspecting and cleaning your battery terminals will help keep your WRX’s electrical system running smoothly. Before cleaning, reference your owner’s manual for instructions on how to disconnect the battery cables. Once the cables have been disconnected, gently clean the terminals with a mixture of water and baking soda, a wire brush, and a rag.
