Trojan t-1275 vs Signature series J150 RE
Before winter, I need to get a dedicated flooded house battery, my Northstar AGM-27 has been working hard as both house and engine battery for the last 4 months, and I want to return it to engine star...

Well, I am Dealing with Trojan, not a fly by night battery company. I found their return E-mail insulting, given all the information i provided they should know they were not dealing with a battery neophyte, but the answer was as if they were.
I let them know my displeasure.
The space I have for a battery is limited. The screwy31 was absolutely maxing out the space. I cut out that battery tray as it was in poor condition anyway. I originally thought just lowering it 1.5 inches would allow me to fit a T-1275, but I found that yesterday this was unlikely.
Moving something else will allow me to fit a t-1275 with a smidge of clearance.
I was aiming to have Solar be my main charging source. I know that Solar alone cannot keep my Northstar AGM happy at 50% depletions, and use the Meanwells 40 amps or my alternator to fill that high amp recharge void this AGM requires.
The Lifeline also has that 20% recommended rate, which my Solar cannot meet, but the Meanwell and alternator can meet that void.
I was really hoping a T-1275 would be the best compromise of both worlds. Really my reluctance is Trojan's that 45 to 75 amps is too much.
I don't want to have to throttle back my charging sources, but my Alternator and Meanwell greatly exceeded the Screwy 31's 10% recommended rate too, and I still got nearly 500 cycles from it.
So perhaps I am just overthinking it in my desire to attain ideal. The t-1275 is still likely the best compromise and should outperform the screwy31 easily, especially as i now have the Meanwell with Ammeter attached where the Screwy31's first 16 months it went without.
PT, Niners report of 23 amps maximum into his tellycom battery from his megawatt has me believe there are fundamental differences in design/intent with these tellycom AGM batteries. I need a battery to accept huge currents at relatively short durations from my alternator and to take all the 40 amp meanwell can deliver without getting petulant or instantly limiting amperage.
The lifeline gpl-31xt and my northstar AGM are impressive in how much amperage they can accept without battery voltage climbing instantly to absorption voltage. I do not want a battery which says Whoa Whoa Whoaaaaa Nellie, not so fast, and limits what my charging sources can deliver
