With the grease on the terminals, the connections to the battery look clean much longer but the problem of "you have to jiggle the terminals in order to start the car" is more likely to happen.
If a car battery's terminals can be jiggled, the problem isn't the grease. The problem is the terminals are loose.
This is an tow truck operator's trick I learned years ago. Find the loose terminal, stick a screwdriver in the terminal and twist, my key ring has a small screwdriver. Then ask the owner to try to start the car. If the battery is good the car will start. Then tell the owner to tighten the terminals. I have done this to stranded motorists and they thought I had performed some kind of magic.
Interesting how the dictionary defines dielectric:
