Hi, was looking at some Wal=Mart batteries for my new Minn Kota electric
motor. I see what looks to be a 12v marine battery, says "deep cycle
trolling" on it, is as big as a 12v. Made by Johnson, but it's called the
"27dc-6".. why the '6'?? is that a 6 volt battery actually? I understand
the 27 and the dc, but not the 6. Should I get this battery?

Thanks!
