Potential converter problem

Not normal to stay in "float mode", it should move to float only after not seeing a draw after some time, like 40 hours. Mine does that. A good battery and functioning converter should cycle in the float and charge mode, shouldn't be in bulk mode.

I am on my second converter in my 2017 model 180. I am very familiar with its operation and monitor it closely with a permanent voltmeter. It is quickly going into the float mode of 13.2 volts while using and living in the unit. The only way to get it into the normal or absorption mode of 13.6 is to cycle the power on and off. I have tried to increase power usage and the fan on the converter will activate but it will stay in the float mode. The 2 batteries were down to 12.3 volts or 70 percent so they weren’t topped off when I removed power. Some might think the float mode is normal but I am skeptical. I am asking for input from the experts. Also I really want the progressive dynamics converter but need to know the model number, does it fit where the WFCO 8955 was, and is the wiring the same. I know this has been discussed but my search of the forum did not answer my specific questions. Thank you. This forum is awesome.
