55 Amp Converter Charge Times
It it possible for a 55 amp converter (with a 14.4 volt quick-charge mode) to take a new Interstate SRM-24 series Marine/RV battery that's discharged to 11.90 volts and charge it to 90% (12.58 volts) ...

The difference is that if you see boost mode (14.4v) the 9 amps into the converter will hold for 60 to 90+ minutes instead of 30 before it starts tapering.
You can check around all you want to check the system and with great effort you may or may not ever see boost mode.
The real measurement is the voltage right off the WFCO converter during the first 2 minutes of charging. This voltage right at the converter needs to be somewhat below 13.2 volts to trigger boost mode and is actually fairly difficult to achive. Been through this years ago. Far better to just get a new converter that works as expected.
X3. Got a PD 9245 and a pendant, along with a short run of some fat wiring, and I am good to go, getting that 14.4 volts bulk mode charge for 4 hours, manually. Good enough for either a Trojan 150AH T1275 12V or group 24's or 27's, when boondocking.
