Duracell Ultra 6V Golf Cart Battery

Earlier this year, we were going to replace the two 12volt house batteries with a pair of 6 volt Trojans. Our issue was that the 6 volts are too tall for our battery tray (under the steps of our Class C). I decided to go with a pair of Duracell group 31's from Sams. Saw them on their website. Went to our local Sam's and they didn't have them. Said they have never seen them there. Called another Sam's club about 30 miles away, they told me the same thing. Went to Batteries + bulbs. They had them. Gave me the online discount at the store and even installed them for me. One of my terminal wires was broken (wasn't aware) and they replaced that as well. Am very happy with the two 12volt duracells so far.
