"Dielectric means that it does not conduct electricity, so it would seem counterintuitive for use in an electrical connection. In fact, a dielectric grease is perfectly acceptable for most electrical connections. You want something that will seal out water and air, preventing both galvanic and general corrosion. In crimps, screw-on connections, and even most plug connections, the clamping force pushes the grease out of the way, settling in micro-crevices and around the outside of the connection where it displaces and keeps out air and moisture."First picture, first thing I notice is the tube of "Super Lube" which is a thermal transfer compound that is not conductive (hence it is called a dielectric).
Commonly used with an insulator for high power components to insulate them, yet thermally conduct to a metal heatsink.
Please do NOT use this on any connections. It belongs as a heatsink compound in your switching power supply, but not anywhere near your battery terminals.

Also, unless you are on a boat, keep seawater away from your connections, it will corrode anything.
This 10 year old article is interesting:
For more than 35 years, Practical Sailor has been taking the guesswork out of boat and gear buying.www.practical-sailor.com
I'm not finding testing in a solution of 30% saltwater to realistic test conditions, unless you are on a boat with a leak.
Unless you are within sight of the ocean, shouldn't be any saltwater, even in humid air. Saltwater will corrode pretty much ANYTHING.
Interesting that the article you linked, and the article that is 10 years old (and linked in the one you posted) came to such different conclusions.
"Best Anti-corrosion Coating
Noalox (aluminum wiring corrosion preventative) and No-Ox-Id (terminal grease), out performed all others by a wide range."
"However, it actually accelerated corrosion on the copper and solder test samples, which were significantly damaged."
Test procedure that says Noalox is bad:
"To find out, we modified a rock tumbler to provide a gentle washing. Testers filled the tumbler jar about two-thirds full with brackish water and mounted a bundle of standard metal samples (coupons) to one end. Aluminum, copper, and brass are galvanically coupled in one sample set, and cast iron and cold-rolled SAE 1020 steel are coupled in another sample set. The setup insulates the two coupon groups from each other, the tie bolt, and the brass legs.
Testers applied a uniform, thin coating of grease to each sample coupon and allowed the coupons to gently splash in the tumbler for 10 days; testers changed the water and cleaned the container daily to minimize grease re-deposition. We then observed and measured both corrosion and remaining grease coatings."
Test procedure that says Noalox is the best:
Unfortunately the testing used in the "best anti-corrosion coating" won't let me cut, it's a PDF.
I think the key difference is not being put in a rock tumbler.
