I am running concorde Sun Xtender AGM's in my TH, as well as in solar projects at work. The oldest in service date is 2004? The RV batteries are 4-5 years old, the only maintenance (other then hosing them off once) was tightening the hold down straps, and plugging the inverter/charger in at the end of trips.
