But when you are recharging off-grid, you don't do a full charge, due to generator waste of gas and time doing the high SOC part at low and tapering amps.
You do 50-80s or 50-90s so you will get sulfation anyway. You must find a way to do a proper "recovery" to true full and desulfation equalize every so often. (If you have solar, you might get to full--depends, but we are talking gen and charger)
This is the same with AGMs as with Flooded because of generator time. Now you have to do a "recovery" with the AGMs, which IMO is not so easy at all compared with Floodeds due to the lack of an hydrometer measurement with AGMs.
