I replaced all the Coach/House Batteries and the Chassis Battery on last Thursday 13Apr17 with AGM Batteries, 6- 6v 220Ah Lifeline Batteries, and I replaced a group 65 Duragold From Auto Zone Chassis Battery. (the chassis battery was replaced in November 2014) All of them were completely dead, and all of the coach batteries were dry as a bone. The Coach/House Batteries were all Interstate U2200 Workaholic 6V 220ah flooded batteries. I bought them in Aug of 2007, I think if I would not have neglected them since January of this year, they might still be working, but then again I was very ill and in the hospital for 10 days in February. So I would say I got my moneys worth out of the Coach/House Batteries.
