I'm replacing the battery in my Dino, I've decided on an Optima, yellow top. That narrows it down to four selections D34 750CCA 870MCA D34/78 750CCA 870MCA D31T 900CCA 1125 MCA D31A 900CCA 1125MCA So, what are the dirrerences in thes, and should I go for maxs cranking amps and longest life on discharge, or what? I do want the deep cycle as the Dino does not have the best charging system in the world, right?
