Another AGM conditioning question
This is my chassis battery, an agm I got used and have little experience with. Trickle charger failed in storage, it is dead as a doornail. Not covenient to babysit it for long hours on meanwell or...
Forum Discussion
BFL13 & MW - Well, at least I get a could chuckle from reading your posts. (Complements to you both, LY is pretty slick with a sentence or two too:)! And I'll cross board post that 757Driver on IRV2 has also been assisting with his familiarity with the battery process. (And one sweet recent conversation to Lithium in his coach. Entegra owner group, search for his handle, and you'll find his new setup.)

So the Campground Host came by when I was out willing the clouds and rain away. Said I should be able to move to the next site, boon docking again, within an hour. He'd talked with the current occupants, and they were scratching their hike this AM due to the slick surfaces on the trails.
So here are my readings of a not fully resting battery.
-Inverter and Charger from the Magnum side turned off since 1:00PM yesterday, until 8:00AM today. So 18-19 hrs of semi resting.
-Solar MidNite Classic 150 Controller turned off at the same time
-The items I consider light overhead drawing (LP Detector, etc.)
-Magnum SOC shows usage of 53AH from last the full charge of yesterday.
Bank = 12.61V
Bat 1 = 6.31 V
Bat 2 = 6.29 V
Bat 3 = 6.31 V
Bat 4 = 6.29 V
Bat 1 & 2 = 12.6 V
Bat3 & 4 = 12.6 V
The lowest two's 6.29 V = ~ 27-29% Depth of Discharge
The highest two's 6.31 V = ~ 18-20% Depth of Discharge
Since the bank dis have the light loads of LP Detector, Fantastic Fan Rain sensors, etc. and the 53AH's reflect going thru the BMK Meter's shunt during this time. I suspect those values would have been a tad higher voltage if I'd done a full disconnect.

I welcome feedback on those numbers. But I think I need to visit the local Home Depot or Lowes, a nice drive from here, and buy another Kill-A-Watt meter. Yes, of course mine is in San Diego:)! Dedicate one to the RV, Under $30, it will be good to have in the RV tool box arsenal.
I've had a few people suggest I get a good reading on what the Samsung is actually consuming, vs what it had been consuming. (A few have reported they needed to have control boards replaced. Samsung still worked, kept things cold, produced those had formulations of water I like to rattle in my glass - but that two of them never had their Defrost mode go off, but to a bad control board.
Either way, it would be good to know if the Samsung is using more then what I tested out to before. (From memory, it would consume 150-165 Amps, over a 24 hour period. With of course the night time 'no solar' being the consumption demand on the battery bank. Say 75-82.5A. That was from 7 days of data Kill-A-Watt values, averaged out for the 7 days. And ambient temps was as high as low 80's, and lows were to the low 60's, and low to moderate humidity.
So getting a reading the current Samsung usage, I'd know for sure nothing is going wrong with that.

I do want input about those voltage readings from this gang. But frankly not as low as I had anticipated.
Going to go get wet now, packing a few things away for the long 2 tenths of a mile trek to the next site:)!
Best to all,
Smitty
