Can anyone tell me the usefulness of this cover. If it’s not that important it might get ditched.

Insulation. Batteries in these die a early death as it is. it's literally to help lower the battery temperature. Some estimates are up to 20 degrees difference.
If you want the battery to get hotter faster, ditch it. If you care about the battery, keep it .
You can imagine with the shape Jeep is in they'd not waste even $1 for such a thing if it didn't help save the battery life. These are very vulnerable to heat issues.

I've not looked it up for Jeep, but on some trucks and cars it's called "battery thermo cover".

Thank you, I was hoping you would chime in, if it would have been something geared to keep warmer in cold climates I might have dumped it but, but if it helps keep it cooler it definitely needs to stay.
Thanks

A couple of years ago or so someone said it was to keep it warm in cold climate - and I'm thinking - how would that work?? When it's 0 degrees for 5 hours, that battery will be 0 degrees even if you put one of my wife's quilts over the whole engine bay. There's no heat generated when it sits to keep in with any sort of cover.
But keeping heat out, at least stabilizing the temperature can be seen.
I can see once it starts "charging" and warming up it would keep it warm, but then who cares once the thing it started and going, there's natural warmth there anyway.

I wish they came in blue for my JT, and reign for my wife's JLU. But I can hear her now "can you see it when driving" No. "Then don't do it". Bummer.

Number one killer of batteries in engine compartments is heat. Aluminum foil insulation also reduces radiated heat.

And you see that all over the place under the battery area around the area of the cat on the right side.

In the past things were protected with simple metal heat shields where there was space or room for them.
The slave cylinder of the hydraulic clutches of the 1980s saw a metal heat shield around the slave and another made onto the line from the master down to the slave to prevent the exhaust pipe nearby from baking the cylinder and line (and fluid)
It was done for carburetors, too - a simple metal plate reflected the heat away from the carburetor.

But anyway, check in up above the right end of the front axle and you'll see a lot of foil-backed insulation wrapped around things.

Agreed. I have had countless hot rods over the years as well as a JK with LS3 conversion and 6L80 trans. I swear by heat shields and the newer foil backed products to keep things from overheating. It's not expensive, it's easy to use, and makes a world of difference in vehicles. Just bought a 2023 JTR and I'm in process of spending / wasting money on it as usual and one of the things I am going to do is install a larger main battery and build a better heat shield than the one supplied. The OEM shield helps but there are lots of ways to improve on it. Getting tired of spending money for batteries that did not live up to their design life in our vehicles. I installed the HotHeads floor insulation package which is foil backed, adhesive insulation on the JK when I had it and was very happy with how much it reduced the heat from the LS conversion thru the floor. Made it very quiet actually.

There's other good examples right there in your post of foil and insulation.
I need to some something about my 73 with those headers and big pipes (and no AC in that car - that floor gets hot)

You are a AMC guy I see. Nice cars. MY HVAC guy has a race AMC that he spends all his money on as well. I made fifty bucks a while back on a bet about American Motors, specifically, that in the late fifties Rambler thought about putting fuel injection in one of it's models. Chevy did it in 57 of course and it was highly successful. Too bad AMC never went beyond prototype with it. I was friends with the local AMC dealer in Oregon at the time and he showed me a picture of the proposed FI installed on a prototype. I think I was in the 6th grade at the time:) Anyway, get yourself some rolls of the sticky-backed foil insulation and give her heck. The stuff works great.

Well I just had a critter get into my engine bay and chew this thing up, then chew up the battery underneath... so I need to replace. Any ideas on a part number for this or an aftermarket option thats as good or better.
