They supposedly were pretty new. Would running one or both of my gennies hooked up for a few hours top them off?
No. A gen just supplies 120v to a battery charger. It is the charger that will top them off. If it can.
If you mean the 12v outlet on a Honda gen or whatever brand, yes BUT you have to watch it like a hawk because the voltage can go way high and you have to stop when it tries to go over say 16.2 volts (Trojan equalize voltage) keep checking the hydrometer.
Once you have them all the way up, that is your "baseline SG" target for future recharges so you know you are all the way full. At that point you can reset your Trimetric AH counter to zero and start over.
