Our Freedom 20 is older, and the manual doesn't mention AGM batteries at all. What it does say is that the gel cell have, "Low internal resistance - the result of this is a higher battery voltage under load, which will result in better inverter performance on demanding high power loads. In addition this allows gel cell to accept a high rate of charge, a plus for rapid recharging".

This led me to believe the gel cell batteries would have a faster rate of charge, as programmed by the dip switches.

Am I wrong in thinking AGM batteries are able to accept a faster rate of charge than gel cell, and therefore a much faster charge rate than wet cells???
