Not to take exception to what you've said, except to consider practical reality (experience) to the argument of "dielectric" grease potentially impeding electrical connectivity where battery terminals are concerned. In practice, dielectric grease (in practice) does NOT appear to impede metal to metal contact within the body of the connector(s).
Although (theoretically I suppose) a conductive grease may be better, it doesn't appear to make a practical difference in the specific application (battery terminals). Furthermore, if one accidentally (or otherwise) applied a conductive grease to a multi-pin connector, the possibility of shorting between the pins would be a real concern.
A whole chapter could be devoted to automotive batteries - and the reasons for them to fail - specifically. But, to cut to the chase, a LOAD TESTER is an inexpensive tool to have to quickly sort out "what is what" in an automotive battery. Once a car battery is fully charged, one can know in 10 seconds if the battery is "up to snuff". (if NOT up to snuff, sulfate and other things come into play - food for another topic).
And, as far as connector oxidation and other crud goes, an electronic connector solvent/cleaner goes a long way to refurbishing "iffy" connectors.
Just sayin!
