As per the title its a new battery and I have some servisol silicone grease, its says for switch contacts, ignition systems but it also says "high insulation properties".Eh - I dont get it why is it used on contacts if it has high insulation properties.Should I not put anything on, or maybe copper grease, vaseline or the servisol. I am only talking about a very fine smear. Or I also have some ACF 50 I could use.
