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 300D’s battery post?

The white, crusty stuff that can accumulate around 300D 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 300D 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 300D owner’s manual for instructions on how to do so.
