Insulation works both ways... Do engines today produce more heat than engines did before? Seems batteries lasted longer before they included their felt "blanket".
Yes. More power = more heat. The emissions systems don't help either. The EGR on the 6.7 is pretty close to the passenger battery.

I'm pretty sure that a diesel has always had an EGT limit before problems arise. That has not changed. If the under hood temps were that much hotter than engines before then they would be having way more issues with plastic melting. Instead they use a ton more plastic than before and you don't have wires melting or fittings melting because high underhood temps.

Well, my old F-150 with the 360 had a 180° thermostat. The engine compartment was huge and wide open - and the battery in it lasted about 5 years, no blanket.
My current truck runs at 200° or higher - all the time. The engine compartment is huge but it is completely packed full - and the batteries lasted about 5 years, with blankets.

Try putting a radiator from a 1997 diesel in a modern truck and it will overheat, guaranteed.

My 460 came with a 195° thermostat from the factory. I have about the same amount of room in the engine bay of my 2022 as my 1995. The 7.3 powerstroke has about the same amount of room in the engine bay as a modern diesel.
That little piece of felt has an R-value of about 1. If you are shielding something from heat you don't use a piece of felt you use a piece of reflective material like aluminum or sheet metal and then have a stabd-off distance. If you wrapped your starter with that to protect it from headers it would melt.

have you actually looked at the dimensions for both? A 6.7 radiator may have more surface area but the core is only 1.625" thick whereas the volume of a 7.3 powerstroke radiator is more and the core is actually 2.1875" thick. Total volume goes to the old school diesel and frontal area goes to the 6.7L. The 6.7 has more crap sandwiched around it so it needs to be bigger to catch more wind or else it would be behind stuff.

Thanks for confirming my statement. More surface area = more heat transfer.

OK, you're right. Ford just makes battery heat shields because Bill Ford's grandma needs something to knit to stay busy.
FWIW - the battery heat shields in my truck are puffy and are not made of felt or whatever you are describing.
I had a bad experience with Odyssey batteries, I would never buy them again. I installed a Genesis dual-battery setup in my Tundra, and used the second battery to power the electronics in my roof-top tent setup in the bed. It was comically expensive.
The Odysseys had a slightly different charging profile than normal FLA / AGM / LiFePO battery. So now you gotta buy a special plug-in charger if you want to trickle-charge and maintain them correctly, or else you might void the warranty. Next, they like to see a slightly higher bulk voltage charge (I think it was 14.9v) than my alternator put out. So I ended up doing a hack to trick my alternator to putting out more voltage just to keep them in their happy place while they were charging. Then after babying these batteries in such fashion, I had one fail catastrophically about 6 months after buying it new. A cell simply died. "We've never seen anything like it!" but they replaced it. Quite a hassle. Then a few months after the warranty expired (I think it was 5+ years old) the other one wouldn't hold a charge, even though it had been babied all its life.
I figured I'd have a pair or Odyssey Extremes under the hood at some point sooner or later, but as the price has gotten ever more ridiculous on all the Enersys built batteries I think $204.xx apiece out the door for the Walmarts is just too practical to pass on. And expensive enough already for what a battery does.
As I just today purchased 2 Walmart EverStart Platinum AGM batteries, Group size 65 with 775 CCA. They have the fold down handle into the top of the batteries.
The date sticker says 1/2025. Looks like the newer batteries are of the 775CCA variety ?
If pictures are needed I could take some prior to installing them within the next few days.
From what I've read is that locking the truck for 8 hours or more will update system to the AGM battery versus Flooded Lead Acid.
Truck is a 2019 F350 King Ranch with 6.7 and lots of other electrical added items. Snow Plow package, heated rear seats, auxilary fast heater (not sure if that is the actual name).
They appear to have them both if you look closely at Walmart's online catalogue. The 775 CCA Korean made ones with solid fold down handle and the 750 CCA Clarios with the floppy side mounted handles, which they sell for the same price but notate as "BOXED" in the description. Not sure what the point of all that is. The Korean made 775 is listed as a "WAGM 65" on the P/N on the top sticker.
This thread was very helpful to me in switching from flood to AGM batteries for my '22 6.7 F-350 Lariat Dually...went with the cheapies from Walmart. The 750 CCA version is what was on Walmart's website when I ordered, but they shipped the 775 CCA version instead (not complaining) to my home within 3 days....same model as @HorizontalHunter shows above. I'm in the Rockies, and they shipped from Anaheim, CA. Everything's the same, made in Korea, etc. Thanks to all of you for your posts!
Absolutely, happy to. Let me know if you want more. I included an end shot as the carry handle is different and the base is tapered instead of horizontal.

Happy to say I just pulled the trigger on a Group 65 Platinum at Walmart, and this is the one (775 CCA) they installed. The funny thing is, they told me they had two in stock (Bowling Green, KY) that were advertised as the 750 CCA. The one in my truck is the 775, and the one left on their shelf is the 750 CCA. I'm not complaining, just kind of weird.
Does anyone happen to know what the amp hour rating is for the 775 CCA version of the Walmart Everstart Platinum AGM? Pictures shown above for the 750 CCA version say 68 amp hours, but I can't find that number anywhere on the 775. I'm asking because I just got one of those Ancel BA101 battery testers, and they want you to input the amp hour rating.

Shouldn’t you be inputing the CCA for a starting battery? Cycle thru the settings until you get to CCA.
