Why is there white, crusty buildup on my 740iL’s battery post?

If you notice white, crusty stuff around the battery terminals of your 740iL, it's likely corrosion.

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 740iL owner’s manual for instructions on how to do so.
