Optima battery question - 10/20/19 09:16 PM
Ok I bought one D31M for my cranking battery and three D34M for my trolling motor batteries, I just now looked at my boat that I am selling and I have all four D31M batteries in it, do I need to exchange the trolling motor batteries for D27 or D31's ? The new boat is quite a bit lighter and supposedly the new trolling motor is supposed to be more efficient, never the less I do not want to run out of juice, opinions ?
