Optima Battery

[vandamit]

Do any of you guys run the Optima Blue top? I'm thinking about getting one, but i'm confused which one to get. do you get the D34M or the D31M.......this is for a trollin' motor. my boat only has a 12 volt so i need one bad azz battery that will last me most of the day if possible.
thanks,
travis

the Blue tops are Marine.....the red & Yellow are standard 12v for Auto & cranking batt's.

if you have the room get the BIGGEST one that will fit.....some only have room for so much.
