You're now sounding like one of Optima's supporters usually called Optima Jim they started using all over the Internet after they started having problems once they moved the manufacturing line. SeriouslyMore speculation with zero empirical evidence to back up the claim of their drop in QC.
There are just way too many problems of prematurely failed Optima batteries coming from all forums so it's not bullshit and it's not a problem of "zero empirical evidence" which is your favorite response to those of us, several of which are in this thread, who have reported first-hand problems with premature Optima failures. You are essentially saying we're lying about such problems which IS bullshit.
AGAIN, I PERSONALLY had THREE premature Optima battery failures, two Yellow Tops and one Blue Top which are the same exact battery with different second post configurations. And that's not bullshit. It's your repeated posts denigrating and denying the validity of our first-hand reports that should be called into question.
And what are forums for if not for reports of first-hand experiences? Based on your "zero empirical evidence" reply to each one of these related first-hand reports you should deny all first-hand reports including your own, right? And it's no Bullshit that Costco dropped selling Optima batteries due to excessive failures which came straight from a large Optima battery distributor's rep who was a provider of non-Optima backup batteries to my company. He was a supplier to me, not a friend.
You keep defending Optima against all our first-hand reports of premature failures saying they lack valid evidence. What bullshit. I'm seriously thinking you're now must somehow connected with Optima.
This is my last Optima battery, notice the jumpers of I added to share the load of my winch between its aux and main top posts. They were the same jumpers I used on my previous Yellow Tops due to its side posts not being up to the pull of a fully loaded winch. I always do what I can to take care of my batteries to insure against failures caused by me.
