Question:

Has anyone known figures for leakage currents for larger 
sized supercaps and for Nichicon Evercaps in particular.

All Nichicon "Evercap" supercaps have a datasheet leakage 
specification of 0.5 mA per Farad of capacity.
That seems substantially higher that other claims for 
smaller sized supercaps. But treating this as uA by assuming 
a typo gives figures that are too low.

eg 47F is either about 23 mA or 23 uA.
