Optima has gone to crap since they canned all their american employees and moved the factory to mexico and quit using new led in the things. THey now are basically an overpriced pretty case with a recycled battery inside. I have the red tops in my gas burner cars and i just had to replace both of their batts in the last few months , again, this is after doing the same thing last year with both of them. Heck, Optima doesn't even trust the things anymore.. Thye used to have 36 month free replacement, then 36 month prorated warranty, now all you get with the things is 36 month and that's it! My friend at the local advance store tells me that they get more Optimas in dead than any other battery, they have better luck with the bottom of the line store brand nowdays, didn't used to be that way. Pretty sad.
They used to make a quality product, but those days are long gone.
