Battery Terminal Cover or Cover Entire Battery Top ?

Right now I have a sealed wood battery tray and no top cover, but I could make one.
I could cover the entire tray with a top.
Or what about the + terminals, what is considered ok?

both a top and cover positive terminal or just a + terminal cover?

I recall thinking of this before, but my terminals were too big for the rubber covers I bought.
If the rubber cover dont fit, you got to a ....
What do you use or make or construct?

And what about battery venting and the USCG? Anything special...

Re: battery terminal cover or cover entire battery top?

Positive Terminal Covers or Battery Covers BOTH OK.
To prevent accidental contact of the ungrounded (positive +)battery connection to ground, each battery shall be protected so that metallic objects cannot come into contact with the ungrounded battery terminal (Pos +) and uninsulated cell straps.
Battery boxes, whose cover forms a pocket over the battery, shall be vented at the uppermost portion of the cover.

Re: battery terminal cover or cover entire battery top?

I was just thinking, I have some really large diameter heater type rubber hose, I think 2 inch.
I could cut off a 4 inch long piece.
on one end, cut a 1 inch hole in bottom of the hose and slit it to the hose end from hole to hose end only on one side.
pull off the positive cable, slip on the hose
tighten up cable and slide rubber hose back over the terminal
the cut hole accommodates the battery terminal and the slit part is forward of that sort of locking it in place and covers the whole terminal and cable.

So the cover simply needs some holes drilled in the top to keep hydrogen gas from accumulating. I think I had made a cover, I might just do both. I recall it fit on top of my tray and was strong enough I could stand on it.

I bought the terminal covers from this company: https://www.vtewarehouse.com/html/commitment.php
Great selection.

Don't battery compartments need ventilation?

yes they do.
Actually I found my old cover, and the top is there and the ends are open. So I think I will put it back on.

It is a plywood board with 2 other boards edge secured to form a U type shape and it sits on the lower box and is strapped together with it. The ends being open allow the big wires to come out and also vent any gases.
