Question For AGM Battery Owners...
Are there folks out there who have decided they do not like AGM batteries and believe their AGM battery purchase was a mistake, and should have purchased standard flooded lead acid batteries instead? ...

Mex,
You know my RV battery story - I've posted it several times:
- Two 12 volt 100 amp hour each wheelchair AGM batteries coming up on about 9 years old.
- Their recommended float range is 13.5 volts to 13.8 volts.
- The stock 13.6 volt converter takes care of floating them in storage (RV parked in the back yard).
- The stock 13.6 volt converter and engine alternator take care of charging them on camping trips.
- I dust them off once every 3-4 years.
- I capacity tested them this winter after they had been connected to the converter continuously for weeks ... at which time I considered them as being fully charged (the ammeter also showed zero current going into them). I then put a 20 amp load on them for five hours. At the end of this extended loading, their terminal voltage after several minutes of rest was about 12.1 volts. Unless I'm missing something, this test showed them to still be in "pretty good shape", capacity-wise.
So far, IMHO, AGM RV batteries appear to be both the highest price and the highest value ... of the two battery types.
