Why doesn’t my 300 battery stay charged?

A battery is in its final hour when it will no longer hold a charge. The battery might be old. Or, you may have been leaving your car doors ajar and the lights on overnight. Stop by for a complimentary battery check at your local Firestone Complete Auto Care and learn more about your battery's charge.

How long can I expect my car battery to last?

The typical 12-volt car battery may last three to five years, depending on the type of battery, the driving conditions, and how well the battery is maintained.

What is the white, crusty substance accumulating 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.

What do I do about corrosion on my 300 car battery?

Regularly inspecting and cleaning your battery terminals will help keep your 300’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.
