Why won'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 may have a habit of leaving your car doors open and the lights on overnight. Stop by for a complimentary battery check at your local Firestone Complete Auto Care and get a handle on your car battery’s health.

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.

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

The white, crusty stuff that can accumulate around WRX 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 WRX vehicle 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.
