the new Optima are debatable.. i've had lots of local guys with extremely bad luck with them since that new-er company took over.. i had a yellow top die in less than a year, got it replaced and the new one is dead now.. i will never buy another one.. even tho they did make it right with a second battery.. the second time they said something had to be wrong with my charging system... and NO there is nothing wrong with my truck.. the new one has been fine for almost a year and still has great stats.
the duralast gold's have been great.. but the Zone didn't have the one i wanted so i got mine from advance auto, idk the brand but its a deep cycle marine/start battery... it was only like $78.99
