Battery options BESIDES Optima?
When "Western batteries" was in Spokane, we used to get stuff re-worked all the time. I haven't even LOOKED at a truck/ equipment battery in years, but back then they were all "tar top.
We used to have all kinds of special stuff done...........
12V batteries with a 6V tap for conversions.........
1 extra cell for operating 12V equipment direct off batteries
and of course having one or two bad cells rebuilt on a battery that wasn't very old.
