Why won’t my 300 battery hold a charge?

A battery that won't hold a charge is almost as good as dead. The battery may be too old. Or, you may have a habit of leaving your car doors open and the cabin light at night. Stop by for a complimentary battery check at your nearest Firestone Complete Auto Care and learn more about your battery's charge.

What is the average lifespan of a 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 300’s battery post?

The white, flaky stuff that can build up around your 300’s battery terminals is known as corrosion. Acid leaking from your vehicle’s battery post can have a chemical reaction with the air, leading to an accumulation of the white, powdery substance over time. Corrosion can affect the flow of electricity between your battery and the electrical system in your 300, possibly causing issues with electrical performance and starting. If left unaddressed for long enough, it may even cause your battery to prematurely fail.

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.
