Not an AGM hater, here. But not a lover either. The sailors over at cruisers forum settled this long ago. (Hint: AGMs were not the winner.)
OK. With automatic, voltage controlled converters, charge time is virtually identical.
The real benefits of AGM are a lack of maintenance.
However, when one performs successive 50-90s or... worse yet... 40-80s... in order to bring them back to 100%, a mild overcharge is required... just like with your typical flooded batteries. Only man, do you have to be careful.
If you always recharge to 100% after each draw, then this is a non-issue and AGMs have value. Of course... at a slight cost in Amp hours per volume of battery.
You're right, I'm wrong, the military and aviation and Rock My RV and Harley-Davidson all use AGMS because they're just too stupid and didn't read that scientific conclusion over at cruisers forum...I stand corrected. Admitting that, lead-acid cells don't have the low resistance of AGM batteries and as a result generate heat during charging. That low resistance is why AGMs charge so much faster (they do) than standard lead-acid batteries.
