I ran Optima batteries for years. I use a battery tender to keep it charged when in the car is parked in the garage. The only problem for me is the size and weight. They are massively heavy. I bought a Bosche AGM battery a year ago. It is made with the plates flat in the box instead of rolled into a spiral like the Optima.
I read somewhere that you only need 400 cold cranking amps to start a V8 engine in a warm climate. So I bought the small one and it is half the weight of the Optima and much smaller too. It's been working great for over a year.
