I'm a former Optima user. I have three dead ones here on the floor trying to figure out how to recycle them right.
I would say that 15 or so year ago when they were made in the US and were $80 new, they were well worth the money and the best that you could do.
Since they have been made in Mexico and are $160 each, they have become a condensed compacted pile of unreliable crap.
I've gone back to conventional batteries. Those are a higher level of crap for only right now. Between three cars, over the past three years, I've replaced 6 of them under warranty. So they aren't anything to write home about either.
Batteries have never been high tech and maybe I personally have too high of a quality expectation but when I have to worry about the Tesla next to me having it's batteries explode, then I tend to think that yes it could be me but it probably isn't. Batteries are just in a world of crap no matter who or where they are made.
Yea...definitely it's me.
