Meanwhile back at the ranch...
Starting from 80% state of charge 6 cells of GC220s will start out at 35 amps then rapidly sag. About an hour's worth of charging with a 40-15-5 amp wheeled charger. Crank up the gen twist the timer dial to an hour and when the gen burps at charger off shut off the generator. At home fill the batteries, connect a battery maintainer and walk away.
A four hour timer is useful for every 2nd day or 3rd day charging. The main thing is to allow a 30-35 ampere initial charge rate. If those batteries started out from say 12.1 volts in the morning an 80-amp charger would be appropriate.
Generators are sorta funny you know: They plug up their ears when someone screams "You are working at 10% load therefore you should last 10 times as long!"
Running a 30 amp charger for an hour makes sense. Running an 8 amp charger for 4 hours requires a straightjacket.
