Exide Orbital is my choice also.
I think the # is ORB78DT-84
Optimas are junk for a few reasons, 1 they dont last more then a few years normally, 2 even if they do fail under warranty you'll have a hard time getting a new one. A dealer in town says to me " I wont take them as Optima will never take care of me after I replace bad battery"
that in a nut shell has kept me far away from them
