What I like about the brass terminals is having zero,zip,nada signs of corrosion on the cables or anything. It's been nice not having to mess with that. On the other 2 auto's we have it's always a hassle. I am using those felt pads with some spray on grease stuff that is supposed to keep the corrosion away but it always comes back after cleaning them up. Not sure the brass is the key or what but it's nice not having a mess!
