I've been using Optima batteries for the last 13 years. I have 4 in the 33', 2 big blues for house and port engine, 2 reds, 1 starboard engine, 1 genset. They are now about 6 years old and holding up well. They are on an automatic charger full time. I also have a small blue top on a small jet boat (175 hp sport jet) that's not getting a lot of use this and last year, battery switch off, no charger, cranks good after several months. I did loose 2 on another boat because the charger died. All in all they have been real good. I should note that I sell Interstate batteries and they handle optima.
