Car manufacturers always fit the +ve battery post with an insulating cover but it often gets damaged and removed. Frequently a second battery does not even have a post cover.
The risk of severe short-circuit is high with an exposed +ve battery post.
So I came up with a simple and effective home-made insulator.
Get a piece of 3 or 4mm thick rubber 200mm x 80mm, use a hole-saw to cut a 20mm hole near each end.
Form the rubber strip into a loop with the holes aligned and place the holes over the battery post to form a tunnel. Place the terminal clamp inside the rubber tunnel and tighten. The cables exit from the open sides.

Needs to be red, then it'll sell like hotcakes lol. Nice idea Allan. I assume it is fun tightening
the nut?

Red? Yes of course ..... now who do I know with red floor mats, hmmm.
Easy to tighten with a socket, but even a ring or open-ended spanner is OK as the rubber just pushes out of the way. An adjustable wrench might present some problem but.

Most good hardware stores sell a product called Plasti Dip , comes in various size tins and colours , paint onto batt terminals after fitting wires and you have your terminals protected from corrosion and any chance of shorting is eliminated as
well.
