If you have the prgressive dynamics converter, it will put out 13.2 vdc in the "storage" mode when your battery is charged and sees little load. In battery specs, this is known as "float" voltage. When your battery is 90% charged, the converter puts out 13.6 vdc and is in the "normal" mode. When the battery is between 50-90% charged, the converter puts out 14.4 vdc and is in the "boost" mode. This is known as the "absorption" voltage on battery specs. AGM battery specs pretty much mirror flooded deep cycle battery specs and can be used interchangebly for house batteries. I ditched my flooded group 27, 75 amp/hr battery for a west marine (made by east penn...think deka) group 31 agm good for 105 amp/hr rating.
