??? Set Points For Different Battery Types
I'm just learning, with a smidgen of comprehension thrown in, set points for charging batteries. Are the set points the same for ALL AGM batteries, for ALL FLOODED/WET batteries, for ALL GEL batter...

I have two banks of batteries in storage. One bank is 2 x 6V GC2. The other bank is three AGM batteries, totalling 100 AH. The banks are currently connected in parallel to a solar charge controller that is temperature compensated. The charge controller briefly goes into absorption mode in the morning (14.8 V) and then maintains a float voltage of 13.6 V. The AGM bank is observed as performing the same as at installation time, three years ago. The FLA 6 V's need water twice a year and specific gravity maintains consistent.
I don't see how any 12V AGM battery could not thrive at a 13.6 V float setting. Some mfgs advise a constant charge regimen much higher (15V). I have experienced an AGM battery opening it's vent. It took an inadvertent 19+V on a fully charged battery for more than an hour to pop it's valve. This was a smaller, 30 AH AGM.
