AGM Battery Questions
I'm shopping for batteries for my new TT and could use some advice on AGM vs 6 volt flooded golf cart batteries. I used the latter on both of my previous RVs and my first thought was to get the same ...

Charge ACCEPTANCE is key. When regular battery absorbsion limit is reached and amperage starts backing down, the AGM will still be maxxing the charger. This phenomenon is pronounced and prolonged. A greater amount of WATT HOURS in (or kWh which is more accurate).
So charger size is a vital component of "Do they charge faster?" You need to understand the voltage/charging curve in relationship to your charger. A 20 amp charger wouldn't do a squat worth of difference nor would a huge charger on a titanic battery bank. Fifty percent of ampere hour rating MINIMUM to take full advantage of an AGM battery's charge receptivity. 100 amperes for a 200 amp hour rated AGM bank. Two hundred amperes to take full advantage of a 400 amp hour bank.
