Chassis grease contains sulfur
Not the ideal mix-n-match with copper
Dielectric silicone grease is light years better especially when it comes to very high temps. But even more important is sealing the junction between the lead battery post and plastic jar lid. The grease has to be applied meticulously to the underside of the battery lug as well as to the morphodite shaped "RV" lead post. Getting -under- the flat section is a chore. The terminals should be outright banned and a 3/8" + 5/16" stainless steel stud used. Anyway arguing will bring forth images of my 100 amp bussbar that was smeared with chassis grease then stored by a friend. "Chocolate" does not quite describe the patina. Sulfur and chlorine are both found in lubes and both are detrimental to shiny brass or copper. Pb does not seem to care.
If thoughts of Kumbayah enter the picture sheep grease, anhydrous lanolin can be used. It works great but has a low melting thresh hold.
