Just as I have commented in another thread, the Optimas seem to be a hit and miss from our members here. Exide is thought to be junk, but my Orbital manufactured in Spain is starting these cold morning without a problem. I’ll see how long the Orbital will last, going on its 8th year, I may give Odyssey a try. With prices going up across the board there, Odysseys seem to be more favorable as the price difference is closing in. I have a need for closed batteries as I tent to drive in dusty conditions which usually contaminate my electrolyte and cause premature failure. I am also sick of electrolyte spilling and corroding the engine bay, each battery no matter what brand leaked somewhat,
Odyssey does say that their design avoids the six pack dead space which yield higher cranking and reserve specs. I don’t know that many people use them, but that just be my next battery.
