Hi Timber Wolf,
You are correct... Trojan SCS225 is 130AH at 20 hr rate.
Sorry about the poor proof reading. However, this battery
has served well and probably has never been discharged
more than about 50-60%.... Of course 2 T-105s is a better
solution but the extra 68+ pounds on the tongue was more
than I wanted. I have the T-105s in the large 5th wheel
trailer that I live in full time and have found them to be
durable and more than adequate for that application =
much better than the two inexpensive 12v in parallel that
came with the trailer. If I get a larger "small" trailer and
stronger tow vehicle I would definitely go with the superior
setup of the two T-105s 6v batteries in series.
