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...

If you don't change your converter, you probably won't notice much difference but maybe a little.
An AGM has a lower internal resistance and will draw a higher charging current for longer than conventional lead acid.
That makes little difference if your converter is running at MAX now.
It may charge at MAX a bit longer but that probably won't get you much.
While they CAN charge a lot faster, it might not be a good idea to push them hard enough to get 5X the speed. And I don't think any charger commonly available on the consumer market will charge with a high enough voltage to make that happen.
AGMs have several small advantages that I think are worth the extra money. Many people don't. It's your call.
