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,...

I believe what I stated above about my AGMs is just the opposite: My AGMs won't take any more current once they're fully charged for dozens of hours on the 13.8 volt converter EVEN WHEN I hit them with higher voltage from the engine alternator.
My AGMs act the same if I charge them entirely to full with the alternator: Once their charging current drops to zero with the alternator (which hits them with 14.XX volts at the beginning just like a multi-stage charger starts out with), then they hit a hard stop on current acceptance. They will not accept any more current, per the ammeter, until I run them down some. They do not act like wet cell batteries.
I keep seeing that 0.00A per the Turnigy whenever I bench test charging my AGMs. They just quit accepting Amps.
The tests I am running now are to determine if the MMS-1012 Magnum inverter/charger is doing what the documentation says. Right now, I am 1:34 into a charge that started with 2min Bulk and already in Float at 0.00A at 13.53V. Abs is a timed 2hr stage and I missed observing the completion.
If I were on a genny, I would see that as low Watts on the KAW and I would be shut down. However, as I am on house power, I want to see what happens during the 4hr timed Float stage.
