A long time ago, a very nice local supplier offered to give us some samples of silk screened heatshrink with our name on them. They ended up giving us like 50 of each color 3/4" x 3". We bend the flat part of the terminal, terminate the wire and then add the heatshrink over the wire end. Once terminated on the battery, we then slip the heatshrink over everything and shrink it. No metal shows with this method.
As I have posted a number of times before, a #10 external tooth lockwasher between the battery terminal and the wire terminal prevents the terminals from slipping and therefore prevents the hardware from loosening. We still have batteries from 2006 (practice only) that have tight terminations using this method. Internal tooth will likely work as well, but I like the added surface area and greater bite provided by the external tooth. A loose connection translates into high resistance and high temperature while also providing a nice intermittent to reset the Crio or radio..
