I am using (2) 6V Duracell GC2 208Ah batteries in series and, after fine tuning my settings during the first year, I wound up making the following adjustments:
Battery capacity: I've found that that in my rig, entering 91% of the advertised battery capacity (in my case, about 190Ah) seems to work well.
Charged voltage: I reduced this from a float voltage of 13.2 to 13.0 per Victron's recommendations.
Tail current (%): This took a bit of of observation using the 712's display on my phone. What I did was to look at the incoming Current value just after the charger switched to the 13.2 float mode. In my case, the display showed my current in float mode to be 0.70A. Since you are entering in a Tail current PERCENT, divide your float current by your (adjusted) battery capacity. So, for my setup I divided my float current (0.70A) by my adjusted battery capacity (190Ah) which resulted in a Tail current percentage of 0.0037. Since the lowest percent you can enter is 0.05%, I entered that value.
