PD4655 Charging Graph
I have been reading quite a bit about different converters and charge rates, specifically some claims that PD's seem to drop off earlier than other brands. That is not what I have noticed on my setup,...

X2 on only needing to get to 90% SOC verses 100% SOC when camping.
I do this all the time and can get 12 or more 50% to 90% charge cycles before I start seeing performance of the batteries start falling off. Performance meaning my length of charge start getting shorter.
That is when I have to do a full 100% soc charge to rejuvenate thing again.
My 90% SOC usually takes right at three hours of generator run time using smart mode charging and around 12 hours to obtain a 100% SOC.
My battery banks pretty much follows the PD charging events listed in their manuals...
"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."
