I found this out the hard way when I left my refrig on DC power on a previous trailer once thinking the solar panels would keep the batteries charged up.
The AGM battery would not accept a charge.
I took it back to Batteries Plus and they had to charge it at a very high rate in order to bring it back to life.
That has been my experience as well. When I have had one get drained right or wrong I use jumper cables from the tv for about 10 minutes and then the charger took over from there.
