Woo Hoo..New AGM Batteries
two of the new ones in their workplace, the battery rack last night 7:30pm meter 12.93v lights and fans running this morning 6:30 am (early for us) 12.62v down 65ampHrs from full i set th...

With an AGM battery, modestly increasing the float voltage -should- result in a mere momentary rise in amperage then flatten out. But the higher setting would be too high..................................because................................
If it was too low, amperage would rise then stay risen for a considerable length of time. This is a BS detector for AGM float voltage settings. The particular battery design has an inherent "correct" float voltage characteristic that proves to be useful for those whom battery lifespan is critical (long term maintenance float). The testing and tweaking should be done with a fairly new battery then adjusted once a year as the battery ages.
I have a 31 Lifeline on float. Because of its mass it greatly resists ambient temperature "tracking". An 84F to 59F daily spread, yields a seven degree Delta T temperature spread. Only a battery post thermistor compensation could resist exaggeration under this condition.
