My Screwy 31
First off let me say I am not stressing over this. It's just a battery, it is only money, it is meeting my overnight needs, but it is displaying strange behavior, and I am curious as to why. So th...

Journeyman7, I already have 3 inch ducting and many 80MM fans for my CAI for the alternator which I never fabricated. It will be a matter of making shrouds to mate them for a closed system to keep the T 1275 bathed in outside ambient air rather than underhood air.
It would be interesting to Autopsy the 31battery, but it is worth more to me as a core charge for the T1275. The bottom of the cells heating due to plate powder accumulation cannot be denied. I assumed it would be more a direct short with voltage dropping to 10.5v or less rather than what it shows now.
The IR temp gun has been an invaluable tool. While voltage under load had indicated performance loss, and wide disparity between SG on the 6 cells also indicated approaching battery demise, it was the excessive temperature accumulation under a low and slow solar recharge which raised my hackles and caused me to take the battery out of service before it acquired full IED status.
No voltmeter or Ammeter or amp hour counter or Hydrometer would have convinced me to remove the battery while it still powered my overnight needs, but the IR gun certainly did. The IR temp gun was the fat lady.
The screwy 31 is now resting well away from my Van, never to return to within it except when I go get the T1275, but it might also be delivered for little more than the gas it would require of me to get there and back.
I'll estimate the total number of screwy31 deep cycles at 485, which, for a car jar pseudo deep cycle, is not that bad, in my opinion. $ per Cycle is the lowest of all previous sets of batteries.
I am liking how my electrical system allows a few flipped switches to accommodate a complete battery removal, with no rewiring required.
I'm really liking the Meanwell rsp-500-15 for the manually adjustable voltage, as it will be doing a lot of 13.6v converter duty, until funds allow me to acquire a t-1275 and return to a 90% off grid lifestyle.
I'm not going to cycle the North$tar AGM needlessly, even though I did last night to see how well it performs. It appears to still have well more than its rated capacity 18 months into use.
