Had to Lower My Solar Float Voltage-Update
Updated 9 July Just a note for folks in a similar situation. My usual procedure in a normal summer here with my set-up with the Eco-Worthy controller (adjustable Absorb and adjustable Float ) is...

The screwy 31 required a lot more time at higher ABS voltages with an even higher finishing stage, when depleted to 50%, compared to when it was recharged from 75%.
Also a higher initial amp rate ( ~25 to 40 amps) from a grid powered charger required lower Vabs for less duration, compared to the low and slow 200 watts of solar on a good sunny day.
I kind of came to the conclusion that any specific Vabs and duration that achieved full SG by 3PM, was only valid for that specific initial depletion level, and every other depletion level, was a compromise using those same Solar controller settings.
But the Screwy 31 was a petulant battery. I am interested in figuring out what a new T-1275 requires in my usage, whenever I get around to acquiring one.
