Help with converter and battery charging...

I almost exclusively boon dock. I have a honda eu2000i and was wondering what is the best way to charge my batteries. I have read that some converters are 3 stage and some trickle charge. I have a WF8935ANP converter. Does this have the ideal charging or would it make better use of my time to buy a battery charger and power it with the generator to top of the batteries. Charging time currently seems very slow. If i should get a battery charger does anyone have any recommendations? Thanks

The best way to charge your batteries is to ensure that the charger can maintain 14+ Volts during stage 2-Absorption of a 3-stage charger. A good charger will have separate cables to sense the battery's volts and temperature and adjust Amps accordingly during all three stages. This is rare for a converter/charger.

The WFCO and so many other converter/chargers only use 13.6V during Absorption. Absorption is the stage where Amps are tapered downwards until float conditions are met.

13.6V will ruin a flooded battery if the Amps are not regulated.

The 13.6V during Absorption is a dead give-away that the primary purpose of the converter is to be a power supply of a nice safe regulated voltage for your RV's electronics.

Be sure to read the charger's manual to ensure that 14+V are applied until the battery reaches float condition.

Float for a battery is when it is time for the charger reduce the Volts and AMPs so that the battery is in stasis. Stasis is when just enough Amps are applied to replace current draws. The 13.6V is ok for float to maintain stasis.
