Which 3 stage converter did you get? What amperage?
I exaggerated on the height needed for GC-2 batteries.
trojan says their benchmark t-105 6v GC-2 battery is 11.15 inches to the top of the threaded stud
GC-2 batteries have nearly the same exact same footprint as group 24.
The Group 24 is just over 9 inches tall. Measure the height of your compartment and see if those 24's are raised on a block of wood or anything.
If it is possible to stuff gc-2s in there you will have @ 50 more amp hours capacity, and the GC-2s are rated for at least double the deep cycle life of a quality marine group 24, all factors being equal.
The GC-2s at sams club, costco or Batteries plus likely cost about the same as marine group 24s.
AGM batteries are lead acid too, as are Gel.
Better term for regular batteries with removable caps is wet/flooded/ sloshy.
If you are only using the generator and converter to charge, well getting the batteries from 80% to 100% takes no less than 3.5 hours when the batteries are healthy, and the longer they cycled from 85% down to 50% and back up to 85% their available capacity walks down, and recharging takes longer and longer from 85% to 100% and might( when new) and Will (when older) require higher voltages for longer.
NObody tries to fully charge batteries running a generator, it is a waste of fuel, and a converter which drops out of absorption prematurely might then take 3 days at 13.6v to fully charge the batteries.
So the converter/charger, plays a huge part, and some are better than others for generator charging, and some suck rancid donkey balls when generator charging is the only charging source.
