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 substance accumulating on my 740Li’s battery post?

The white, crusty stuff that can accumulate around 740Li 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 740Li 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 740Li owner’s manual for instructions on how to do so.
