Corrosion on terminal

Many vehicles have a battery condition sensor integrated into one of the terminals and, for them, grease would not advisable.

I had a car come in with a burning smell and erratic fault lamps among other electrical gremlins. That battery sensor on the terminal suffered an internal malfunction from a manufacturer error, causing high impedence and arcing. I last measured the terminal's temperature at 226 degrees centigrade with my calibrated infrared pyrometer, and it was continuing to soar.

Had that car's terminals been coated with grease, it might have been on the news instead of my hoist.

Battery condition sensor should be sealed and waterproof. Grease wouldn't affect it. Usually is a box after the terminal, so you wouldn't grease over it, or spray all over it anyways.
