Just got my Battery Tester. Never used one. I had the battery tested in one minute. Here is what I got.

Great device.
I tested from the Lugs under the hood, not directly on the battery.
Upon placing the red clip on the copper stud and the black on the provided frame ground stud the tester read 11.6 volts.
Upon pressing the load for 10 sec the needle dropped down to the yellow zone (weak) at 9.8 volts.
Now waiting for battery charger, due Monday.
Dealer service visit Tuesday.

Going to an appointment today with the Dealers' Service Department, 1/10/23, for Deep Sleep Mode. Read above.
Fords' blogger lined me up with a Ford Rep who emailed and will be watching developments. I purchased a battery charger but did not use it yet. I am giving R&D their Day first.
Build date of 3/10/22 is precariously near the Harness Debacle Date. Here we go, stay tuned.
Ford said:
"Just wanted to reach out to you to let you know that I will be your case manager in regards to the current vehicle concern that you are experiencing. Can you please let me know how you’re wanting Ford Motor Company to assist you. "

My reply:

Build date: 3/10/22
This is nice to hear. I go to the service dept. Today, Tuesday, 8am EST.
The vehicle is shut down into Deep Sleep Mode, again.
I did not charge the battery. I wanted service dept to get
their shot. I also experienced the mode in November, but was temp cured
when the dealer treated it at my first oil change.
The big December chill brought back the Deep Sleep Mode.
The only difference with this slumber is it took out my
dash illumination. (i.e. I can't see the speed or battery activity.)
The Truck is perfect for me, please fix. I understand first generation
has growing pains. This is my only vehicle, I am single. Just don't
abandon me. If you know there is a problem but don't have a
fix yet, I know you're working on it. I did not use my battery charger yet.
Looks like extras needed for hybrid:
battery meter, battery tester, battery charger and a NOCO.

Just picked up my Truck from the Dealers Service Dept. It was not the service manager,

I think it was a mechanic, informed me of his work and theory. He re-installed the instrument cluster software and the dash lights came back. They called and they returned the Truck. I shut it off and got a Deep Sleep Alert. I called, they explained about how the computer works,...etc. I ask if the battery had been charged. GIANT QUESTION MARKS ON THE FOREHEADS. So I got my Truck back

with the dash on, for now and my Truck sending me texts about Deep Sleep.

Imagine that. I wonder. Looks like third time for Deep Sleep.

That tester doesnt read amps it reads volts. Amps is current draw (a load). If your tester read 11.6 volts with no load, then it is weak. A fully charged lead acid battery will read 12.6 volts. That is why when you load tested it, it dropped down to the weak zone.
I would fully charge the battery, then test daily to see how fast it is draining. If it drops to 11.6 within just a few days, its probably a bad cell in the battery.

Thank you for the correction, you are 100% right. I need to proof better. Edit done.

POSSIBLE "DEEP SLEEP" FIX, I DON'T KNOW, YET
Dealer Visit was fruitful, they reprogrammed what they called the Instrument Cluster, because my Dash Lights were out. My dash lights are now back on. I can see how my MPG are not my MPH. While the truck is in the Service Bay, the Mechanics are turning on and off the truck, it is sending me "Deep Sleep" texts every time it goes off. They did nothing towards the "Deep Sleep" problem other than if it is in the software reload. "Sleeping" again this morning so I took it for a 60 mile ride. My cab lights are now on and no "Sleep" texts. So was it the "Cluster Reload" or running for 60 miles for charging (my bet the 60 miles). But
