Why doesn’t my Monaco battery stay charged?

A battery that won't hold a charge is almost as good as dead. It may be getting old. Or, you’ve been leaving the doors slightly open and the cabin light at night. Stop by for a complimentary battery check at your nearest Firestone Complete Auto Care to learn more about the state of your battery.

What is the average lifespan of a 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.

What is the white, crusty stuff around my Monaco’s battery post?

The white, crusty stuff that can accumulate around Monaco 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 Monaco vehicle battery?

You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your Monaco owner's manual to learn how to disconnect the battery cables. After disconnecting the cables, use a mixture of water and baking soda, a wire brush, and a rag to carefully clean the terminals.
