Why won't my Mustang battery stay charged?

How often should I replace my car battery?

You can usually get three to five years out of your car battery. However, battery type, how well you maintain your battery, and your driving habits can all affect your battery’s lifespan.

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

If you notice white, crusty stuff around the battery terminals of your Mustang, it's likely corrosion. A chemical reaction between battery acid and the air can create a white, powdery substance that builds up over time on the terminals. This buildup can interfere with the electrical connection between the battery and your Mustang’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

What do I do about corrosion on my Mustang 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 Mustang owner’s manual for instructions on how to do so.
