PD 9260 how long to charge?
I've heard that people with the PD9260 (or similar) use the pendant to force the charger to stay in boost mode (14.4V) while running their genny. To get Max charge with min gen time. Ok, but how do...

If you have a SMART MODE BAttery charger with ay least DC Current between 17AMPS to 20AMPS DC available then any deep cycle battery will charge up somewhat like PROGRESSIVE DYNAMICS states in all of their brocures...
"Progressive Dynamics ran this test on the amount of time it took a PD9155 (55-amp) converter/charger set to three different output voltages to recharge a 125 AH (Amp Hour) battery after it was fully discharged to 10.5-volts.
14.4-VOLTS (Boost Mode) – Returned the battery to 90% of full charge in approximately 3-hours. The battery reached full charge in approximately 11 hours.
13.6-VOLTS (Normal Mode) – Required 40-hours to return the battery to 90% of full charge and 78-hours to reach full charge.
13.2-VOLTS (Storage Mode) – Required 60-hours to return the battery to 90% of full charge and 100-hours to reach full charge."
battery science at work here - not many ways to get around the times listed above.
The battery will demand how much DC current it will draw from the charger. Doesn't matter if you are using a 60AMp or 80AMPS battery charger as the each battery you are charging will only draw 17-20AMPS each when hit with up to 14.4VDC charging voltages.
My three 12V 85AH Interstate batteries in parallel seems to charge at 52-53AMPS DC from my PD9260C Converter/charger and they get to the 90% charge state in approximately three hours time.
If you use more than 14.4VDC charging voltages then you will run the risk of boiling out battery fluids when being charged for a few hours. Starting out with 14.4VDC for two hours then dropping back to 13.6VDC for another one hours time period will give you the 90% charge state and NOT boil out any battery fluids.
