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.

Why is there white, crusty buildup on my S40’s battery post?

The white, crusty stuff that can accumulate around S40 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 remove corrosion from my S40 car battery?

You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your S40 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.

Check your battery regularly and replace it as needed so it doesn’t leave you and your Volvo S40 stranded. Pay attention to clues that your battery is on its way out. A lagging starter, an illuminated battery or check engine light, swollen battery case, corroded battery posts, or dim headlights can all be signs that your battery needs attention.
