Do AGM's charge quicker?
Looking to cut generator time. Have solar but sometimes have little to no sun when dry camping. Read AGM's charge up to 5X faster than flooded. How can that be, converter charger only puts out so mu...

It might be helpful if we quit using the phrases "bulk charging" and "absorption charging" of batteries.
From an electrical point of view, it's more clear to say "constant current charging" (instead of bulk charging), and "constant voltage charging" (instead of absorption charging).
The constant current charging phase means supplying a high constant current for awhile holding whatever (high) voltage it takes to do that, while the constant voltage charging phase means holding a lower constant voltage while supplying a continuously tapering amount of current into the battery until the battery's intrinsic voltage equals whatever voltage that the charger was holding.
For me at least, the above is a lot clearer way to be discussing battery type/size, versus charger mode/capacity, versus charge time issues. I notice that a lot of the technical papers on battery charging also use the terms constatnt current charging and constant voltage charging.
