Optimas seem to run hot and cold........some people have great luck with them, others don't. My Son Don has an Optima in his T bucket and has to keep a trickle charger on it constantly or it goes dead. I had the Odyssey in my 23 (the smallest they make, 7 x 7 x 3 inches) and it could sit for months and still cranked the 350 Chevy like gangbusters.

I heard a story that Optima moved their plant to Mexico without letting their American employees know they were not training the guys in Mexico to set up a second plant.......it was their jobs they were training them for. Don't know if that is true, but it is enough to keep me from buying one.
