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) ...

If your 55AMP converter/charger is the WFCO WF-8955 then just note not many folks can get those to go into the BOOST 14.4VDC charge mode. I never could get my WFCO WF-8945 to do it so I replaced it with the PD9260C 60AMP converter/charger. It works everytime now...
If you want to get it charged in a three hour time span then you have to use 14.4VDC with a current capacity of around 20AMPs. When the GP24 Interstate battery sees 14.4VDC it will start drawing around 20AMPS DC from your converter/charger. The 14.4VDC will stay up around two hours and then switch down to 13.6VDC for an additional hour. Then you will be at your 90% charge state.
If you are only putting 13.6VDC on the battery terminals it will take those times listed in the PROGRESSIVE DYNAMICS Brochure report listed under the 13.6VDC side.
The battery will determine how much current it wants to draw. You just have to have that much current available to use to get the times noted in the report.
