I got them as my trolling motor batteries and love them, thinking about replacing my 31 series optima that is crapping out on me with one of the Sams Duracell’s. My blue top has never failed me, but is starting to turn my 225 pro xs over a little slow. I have a 2015 225 pro xs and 2 lowrance 12 inch graphs and then my livewells. I fish a lot and fish a lot of tournaments. Just looking for some feed back on this battery as a cranking battery cause it barely meets the minimum requirements for my outboard. Thanks fellas
