Here is another bad luck with Optima lately, I finally gave up on them, have one old one that just won't quit, and I used to swear by them, but the last two years I've had nothing but trouble with two I bought, I finally gave up on them when the guy at the Parts store got tired of exchanging them every two or three months and offered to just give me cash credit toward any other battery he stocked, I took him up on that deal. I believe the quality has dropped on them in the last couple of years.
