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.

What is the white, crusty substance accumulating on my FX45’s battery post?

The white, crusty stuff that can accumulate around FX45 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.

What do I do about corrosion on my FX45 car battery?

Regularly inspect the terminals and clean them with a mixture of baking soda and water, a wire brush, and a rag. Disconnect the battery cables before cleaning to help avoid the risk of electrical shock. Always reference and follow the instructions in your vehicle owner’s manual prior to disconnecting the battery cables.
