Trojan's own group31 is rated at only half the cycles as the T-1275. 600 vs 1200 cycles to 50%
If powering an large inverter near its maximum is not a concern, the T-1275 is the clear winner.
...
And T-105 6V GC2s are even better, around 1700 cycles to 50%.
Guess that's the compromise between a true deep cycle battery and a "Marine/RV" 12V battery: # cycles to 50% versus V sag under heavy load. Like Mex says ...
Maybe the T-1275 12V deep cycle is somewhere in between two T-105 GC2s and Trojan's SCS225 "Marine" 12V.
Can C.A. or C.C.A. be used as measure for V sag? Prolly doesn't matter as Trojan (and others) don't even list a C.A. or C.C.A unless they consider the battery a "Marine/RV" battery.
I hate compromise. Maybe I'll just wait for LiFePO4 batts to fall in price.:(
