Optimas are ok but I think their quality has gone down ever since interstate bought them. I am on my third optima in 5 years. I had one red that lasted 3 years, I then had a yellow that lasted a little over a year, and I am on my second red top with around a year on that one. The optimas do not like to sit with a car that does not get driven a lot. If I don't drive my cobra at least once a month the battery will be dead and I have no battery draw in my car, so I had to buy a battery tender. Sad part is I never had that problem with the cheap little motorcraft battery I use to run in the car.
