I drew battery down to 12.1, started charging. Started out 13.3 then 13.6. Amps were dropping; first 51 then down to 35 still at 13.6. So apparently not enough to get to boost mode. Unplugged from shore power, all lights turned on now and will get down to 12.0 or less before trying again.
Pendant ordered and will be here Tuesday.

Yes it is a HUGE DIFFERENCE and that's why I'm trying to figure out why my PD9260 does not go into boost mode. I have no clamp-on amp meter, but amps do show in my Trimetric. I haven't looked at amps in the Trimetric other to see that they are higher when the converter 1st starts, then tapers off as time goes on. My battery was about 35% discharged, a significant amount. I expected the PD9260 to start out in boost mode, then drop back to absorption rate, but it doesn't.I totally empathize with your frustration. Before I purchased the PD9260C, I tried everything to get the WFCO8955 into bulk/boost mode. It was so frustrating to have to spend almost $200 just to get the bulk/boost mode the WFCO8955 was designed to deliver in the first place.
Do I have to discharge the battery 50% to get boost mode, or 60%, or 70% ??

That way you will know when it's in boost.
And if not, you can force it.
Might just do that now that I know it won't come on untill battery WAY DOWN!

With discharged batteries (12.1 - 12.2 vdc) I've found initial charge current with my PD9260C to be roughly 25-30 amps in absorption mode and 55-58 amps in bulk/boost mode.

It takes time for battery voltage to catch up to converter voltage.
When I set my meanwell rsp -500-15 to 15 volts, then attach it to the battery. The voltage at the mw terminals drops to mid to high 13s and battery voltage is likely a volt under that.
Where are you measuring voltage at?
A clamp on dc ammeter is enlightening. Voltage is deceiving.
I am measuring voltage where the battery cables enter the PD9260. I have 2 other monitors, one of which came with the trailer (with the idiot lights for the tanks) and also a Trimetric 2030 monitor, measuring at the battery.
