I purchased two Les Schwab deep cycle batteries last spring. I wanted freshly manufactured batteries and got two manufactured the same month as I purchased them. So far they are serving us well. Obviously I have not owned them long enough to know how they will serve us over the years, however, I use a battery maintainer when the trailer will be sitting more than a few weeks. I have purchased many other products from Les Schwab over the years and have always been satisfied with their service, price and warranty.
I agree with Bryanl. The PO did not maintain the previous set of deep cycle batteries correctly and they didn't last a year.
