T-125 (6v) vs T-1275 (12v)
Mex has been explaining the diffs between 12v and 6v deep cycle batts in recent threads, but there are still questions. With two of the 6s (66 lbs) that is 132 lbs for 240AH (20hr- 12a), while tw...

There is another Trojan L16 (B something?) that has no figures except the 370 20hr rate, and a 100 hr rate !!! of 410AH which would be a 4.1a rate. So you can go five times longer with 4.1a instead of an 18.5a draw
That one was 17 11/16" tall weighing 118 lbs while the L16E is 16 3/8 " tall weighing 100 lbs.
Suggests the L16 B is meant for a long time at a low rate. the L16E has the same sort of AH per lb as the others at the 20hr rate. 370/200 = 18.5 AH/lb.
No idea how many of the pounds in each case is lead vs electrolyte and comparable exposed plate areas, and spongy-ness (?) of their surfaces to increase area. That is Mex and PT territory and might even lead to incomprehensible talk of "watts."
Most of the trojans have a 100hr rate spec. T-125's are 266AH, for the L-16 the L16H is 435AH@20hr, 488 @100hr. The t1275 is 166 @ 100hr.
The 1275 and L-16, along with the others have a 5hr rate spec, and spec's for minutes @25A and 75A T1275 is 70 minutes @75A, 285@25A
L16H is 245minutes @75A!! 4hrs.!! 935 minutes @ 25A!
