Correct if you coat the terminals before attaching the cables. I usually coat the area with conductive grease around the base before attaching top post connectors and on the top after connecting to prevent any air from getting in that could cause oxidation. I also completely coat the area surrounding the clamp bolt. I coat the perimeter of side post connections before making them and the visible area after making the connection.So when I rub regular old grease on my Batt connections am I not getting as much current/flow and/or ground?
Works even better if you solder the coonnectors after crimping them & use conductive connection grease on assembly.I used 4 ga power cables from the stereo shop. Some auto parts stores sell 4 ga and 2 ga power cables by the foot. Be sure to get copper end connectors. I used crimp-on ones. I used a big pair of pliers and crimped the daylights out of them. Much better than regular woven grounds in my opinion. Welding cable would be fine as well.
