I was looking at sears diehard AGM group 31 marine.
Its 13 inches long, standard 7 inches wide, 9 inches tall and weighs 70 pounds.
Electrically it has a reserve capacity of 205 minutes. Reserve capacity is equal to 85 amp hours if the power is used at 25 amps for 205 minutes. Or 92 amp hours at one C over 10 hours (That works out to about a 9 to 10 amp load). And 100 amp hours if you stretch 1C over 20 hours (about a 5 amp load).
There is no way it will fit my current battery holder.
I think I am going to buy it anyway and play make it fit with my plasma cutter.

The optima battery by comparison had 100 minutes of reserve capacity, or about 40 amp hours.
