I just replaced my Magnatek 6300 with a PD9245C. That is the one with the charging wizard.

I don't recommend that for the non-electrical/non-mechanical. person.
I removed the 6300 and removed all the internal mechanisms perserving
the case. I needed it to mount the cover in the TM. I had to cut holes in the case for the PD9245C to fit.
It is a bit too tall.
I also had to figure out the wiring, since the diagram provided in the docs did not match the actual wiring of the TM.
All in all, I got it working and it does fine and is very quiet.
I advise checking the appends by KSBASS. He had good luck with the PD9260C. I believe it fits the case much better.
The reason for the replacement was that the old converted/charger was overcharging the battery. I now have a new battery and new charging system. I'm planning a cross country trip and need the battery fresh while dry camping. No fun dry camping with a dead battery.
