Desulfating with Harbor Freight charger

Man oh man, voltage readings to a flooded battery state of charge is like trying to managing a check account "successfully" by having no overdraft notices arrive in he mail. Temperature the type of recharge before storage all affect how voltage "degrades" in storage.
For storage maintenance it is very hard to beat a battery maintainer that is temperature compensated. If you don't have a socket use a solar panel and float controller.
A battery that is floated rather than let sit to allow a 10% discharge decay, then properly recharged to 100% will live longer than the "maintenance cycled" battery. It depends on the battery and the weather, but adding 20% to the lifespan of a battery by temperature compensated float maintenance would not be unusual.
Don't get this confused with my preference of using higher voltage to recharge flooded batteries that are heavily cycled and recharged with a generator. This is a work recharge and what you are doing is storage maintenance.
If you absolutely must cycle charge in storage maintenance I would let voltage decay to 12.55 then recharge at 2% of amp hour rate until voltage reaches 15.0 then terminate. It would be silly to try and do this with a generator. Yank the batteries and sit them next to a plug, and then get a battery minder.
Perfectly good plate surface belongs on the plate and not in the sediment chamber. Weigh this against I feel my money belongs in my wallet and not in the bank vault of some titanic oil company, and generator manufacturer in Yokohama, Japan.
Do you have electric power close by? Is the rig parked in an enclosed building with no power available?
Or is a Battery Minder in your future? You can run a "topping charge" once or twice a year on a floated battery and keep it in tip-top shape.
