Did the screwy31 thread really reach 100 pages?
The T-1275 should certainly prove to be a superior battery to the USbattery Screwy31. Trojan's own group 31 likely would do better, but my source for either, the price is the same for the 31 or the t1275.
I was a little late to the maximum SG party with the Screwy31, 2 months after purchase I noticed voltage tanking with not many AH removed and then the acquired hydrometer revealed the Abs duration and height to be too low for too little. the turkey baster also revealed the screwy31 to be a masochist though. 14.9v for 3 hours then 15.3v the rest of the day. That is hideous!
But it did inspire great back and forth and lots of learning on how to find an individual batteries sweet spot in a certain usage, and ~465 deep cycles before removal from service is not too bad. Heck it is not dead yet. I stuffed 27AH into it yesterday so it can power fans and lights and Tv in my workshop.
I hope to treat the T-1275 right from cycle number one, and hopefully it does not need to be top charged every day with a 15.3v float/finish voltage and equalized every 14 days for ~ 2 hours at 16v, like the screwy31 did.
That battery wasted so much juice getting to 1.275+ it was criminal.
I was so impressed with that lifeline GPL-31XT that it is hard to not desire that, but the T-1275 is half its price, 25 more AH, and lets me collect more data.
