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...

LY,
I'm checking regularly for temps using infrared gun. 75.4 - 76.3 measuring each cell among the laser light at the center of the cap. (Well, not the cap, but the plug where caps would be on a cell. Sometimes the center cells are tad warmer then the outside cells of a battery, but within .2F of each other.
My source for charging is the Magnum MS2812, I'll read the various manuals again to see if I've missed a setting. But the only way I've found to set a voltage and have it go in at that specific voltage for a given period of time, is by Equalizing. I've set the Custom profile to 14.4V, which matches the Absorb setting to. The MS2812 when set to Equalizing, runs 4 hours. The ARC50 Remote, displays Equalizing and gives voltage 14.4V and Amps. When the Equalizing shuts off, or now I'm shutting it off myself when it's over 3 1/2 hours, and then I 'restart' the Equalizing. The Amp display ups to 26-29A, then over a 10-15 mins, works down to the teens. Usually to 15A, though this AM when I went out to stop and restart the Equalizing - it was 19A. (On shore power, and the Inverter in the Off position. So minor parasitic draws on the house bank.)
I have power until 10:00-11:30AM tomorrow (Friday), when I must move to a boon docking site, so I have about 28 more hours that I can keep doing the feed of 14.4V. But we then bounce back to a Shore Power site for one more day on Saturday. So I'll do the 14.4V feed again as long as I can on that move. We move Monday to a boon docking site for the balance of our stay at Lost Dutchman State Park which is Friday 3/16. And the 10 day forecast is Cloudy and Partly Cloudy for that period. So will use Generator and Solar to keep the batteries up.
I will double check my MidNite 150 Classic controller settings, but pretty sure I can change the Absorb time. 14.4V, to run longer. I'll set that for as long as it allows me.
The other thing I'm trying to find, is how to get into the Magnum ARC50 to see the Magnum's last record of Reaching Full Absorb. I saw that on one of the drill down's while scanning the manual PDF, but the 03x settings are a bit different because of the BMK Meter. So have not been able to find the last time that Magnum recorded a Full Absorb cycle. (Maybe it's not available with the BMK Meter module in the mix(?) - but still checking the various manuals.
As I finish this post, I just looked and the ARC50 is displaying Equalize 14.4V and fluctuating between 19-18A. Which since I've not drawn any power to speak of out of the battery bank, is probably not a good sign. As it had held 15A for several hours as I monitored it off and on during the day.
Best to you and all,
Smitty
