Naw, flipped + and - sides.
FWIW, my Yellow Tops are still good after being run down flat a couple years ago from welding at Jenny Creek (the winch point) without recharging them. I recharged them over, say, about a week or so and they have come back up and stayed up. They are around 5 years old or more.
Good to know about the Sears batteries though. I am pretty much forced to use glass-mat batteries, as they are mounted on the side under the deck in the rear. The Duralast story too.
