I've seen them cut in half so many times and you are better off with a name brand store AGM or an Odyssey or XS Power. At this point you are paying for a name nothing more.
When Optima first came out in the '90s they were a good battery. Since they got sold off a couple times eh nothing special about them anymore.
I know one person who disagrees on them being junk here but after seeing them cut in half and being promoted by their sales reps when I used to manage auto parts stores, I saw the same or worse components in the cheap AGM's we or other store sold only Optima wanted 300-400 bucks for them vs the 150 bucks for the store brand.
There is only 4-5 battery companies worldwide. You might be surprised at who makes what these days.
