I just switched to dual 6V batteries and from the research I have done, my WFCO 8955 converter has some design flaws in it that will inhibit efficient charging of the batteries. It seems that the WFCO units, although "3-stage" don't actually go into the Bulk mode which is needed for quick charging. It also won't drop down into Float mode, which will cause the batteries to boil down over time.
I just ordered the Progressive Dynamics PD9260C which has the Charge Wizard and will give the battery exactly what it needs, when it needs it.
