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...

Who knows how long to BOOST charge your batteries.... The Wizard knows (Sorry Mr. Cranston)
Though the 9260 is capable of 60 amps. Rarely will you get full output.
Here is a formula, you will need to plug in the proper numbers, Amp hours are at the 20 hour rate.
(Total amp hours) * (100%-(State if charge)%) = (amp hours to replace)
(Amp hours to replace)/50 is a good estimate.
Example: pair of GC-2 230 amp hour at 60% state of charge
230*(100-60)% = 230 * 0.4 = 92 amp hours
92/50, a bit less than 2, so 2 hours (you may round)
Seriously though, the Wizard may take over when the proper level is reached even if you initially overrode it and forced bulk.
From the point where it goes to absorption, another 2-4 hours to fully charge, but if you are boondocking,,, You may wish to skip that last 10 percent SOC.
