Why doesn’t my 300 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 been leaving your car doors ajar and the cabin light at night. Stop in for a free battery check at your nearest Firestone Complete Auto Care to learn more about the state of your battery.

How long can I expect my car battery to last?

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, crusty buildup on my 300’s battery post?

If you notice white, crusty stuff around the battery terminals of your 300, 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 300’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I remove corrosion from my 300 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 300 owner’s manual for instructions on how to do so.
