The first Optima I had was a red top about 7 years ago. Awesome battery, used that same battery in my truck to go to the lake, then would pull it, stick it in a miller 454 with no alternator. Run it all weekend then back in the truck and drive home.
Since then? Almost every Optima I have bought has been a disappointment.
Seem to ALWAYS be dead and nonchargeable. I don't know what the deal is.
Yellow, Blue, Doesn't seem to matter. I keep hoping, but I am going to look elsewhere next time. Maybe it is me killing them somehow, but they just don't seem to be as good as they used to.
