Problem with one battery but they replaced it so I am happy.
I ordered (2) 100ah Group24 batteries and when I received them one worked great but the other one would not accept a charge or power any 12 volt device even though it showed a 13.26 volt charge with no load. As soon as something was connected to it the voltage dropped to less than 1 volt. It took some time working with customer service to take care of the issue but they did send me out a new battery that worked just fine. So in the end I am happy with the batteries and so far they have been working great in my RV.
