So I just went through yet another Optima in my buggy. SO, I need to get another battery. It needs to take vibration since it's in a buggy and its in the passenger compartment so it needs to be a sealed dry or gel cell. Since this is the third optima I have been through, I'm kinda weary of getting another. Whatcha run, how long have you run it, and how much did it cost you then/now? Looking for ideas.
