I started using my PD9260C in 2009 and have been using my home made BATTERY MONITOR Panel which has two 0-30DC VOLTMETERS and one 0-75 DC AMP meter on it out in plain view when I am camping off the power grid. The two 0-30VDC meters are tied each to a battery bank of two batteries. Of course most of the time I have both banks switched online so both meters read the same DC VOLTAGE most of the time. When running off the batteries I can watch both battery banks slowly start dropping from the 12.6-5 VDC level down to the 12.0VDC level.
I have never really worried about the exact DC VOLTAGE I read but for the most part I either see 13.6VDC or 13.2VDC when connected to shore power. When connected to shore power or generator when smart mode charging kicks in I see 14.4VDC for about an two hours and then it drops back to 13.6VDC after that. If I am not drawing any current it will drop to 13.2VDC. As soon as I turn on anything it immediately jumps back up to 13.6VDC.
My GP24 12VDc 85AH Interstates batteries have been doing just fine since I installed the PD9260C. I started with four of these batteries in 2008 and lost one right away from being over charged with my older single mode converter/charger. Boiled out the fluids and shorted the cores.
I have been running the remaining three Interstates ever since with no problems using the PD9260C.
When I start using my generator powering up the PD9260C after running down my battery bank to around 50% charge state and the 14.4VDC Mode starts up I see around 53AMPS on my DC CURRENT METER. This stays at 53AMPS for about 15-20 minutes and then starts slowing tapering back. after around two hours it is at around 7-8AMPS DC current. Then my PD960C drops back to 13.6VDC which shows around 6AMPS DC current on the CURRENT meter for an additional one hour charge to finish off at around 90% charge state then.
I do this routine every morning around 8AM when camping off the power grid. Once I get in around three hour of charging with the generator connected to the trailer then I am good to go again for the next day/night run off my batteries. If my batteries are not up to the 90% charge state then they will start dropping off alot quicker and I end up having to shut down the batteries before 8AM the next morning as this is usually the earliest time when I am allowed to run my generator here on the East side of the US. I have an alarm that starts beeping when the DC LINE drops to its 12.0VDC mark.
