My last small carbon/aluminum cells output 94mV on DC, and 1.250 or so on the AC setting on my meter.  So, the AC setting shows a higher output than the DC output, sometimes almost twice as much. But, the leds will still only light to the same intensity regardless of what the meter reads.

Please check your meter.
It is probably broken on the DC settings...
It should at least show 0.5 to 0.7 Volts on the DC side !

    Stefan:
   Thanks,  my mistake,  I should have said 0.94 volts DC,  and 1.250 or so, AC. 
    It's me that is a little broken...  my meter is fine.
    Glad someone is on their toes...

 I just tried the epsom salt potassium and borax with carbon and the cell initially hits 1.29 after creation but it still isn't cool all the way. That carbon seems to have increased the voltage output. I haven't tried the current yet. I'm gonna let it dry fully before testing it this time.

In cooking it I had to use a tad bit of water to get the crystals to start melting once that is done you don't need anymore. When dealing with this stuff it would be better to melt it in a double boiler and mix it thoroughly. I might get a mixer with the blades on it like the blades on an end to an mixing shaft that is hand held. This might mix it more thoroughly then we could just pour it into a mold/case(Aluminum or Magnesium). I'm going aluminum because it is more available in every area. This way you can make an insert on the end of the center graphite lead to put put a plastic plug and insert that into a hold on the bottom of the can/case. But that is a bit off in the future. I'm still waiting for it to dry so... We will see...

After 10 minutes cooling it is at 1.27 volts dc...

The mix has a tar like look to it. A tad bit opaque almost candy like consistency.

After 1 hour the voltage is 1.26 volts dc.

   Thanks for your reply.  Yes,  it would be very good to be able to prove that there is such a thing a non-galvanic cell.
   
   At least we need to give Ib some credit in doing his best to show what he has already shown in all his videos about his cells not catering to galvanics. He has put them through the ringer.
   It looks like the galvanic cells stop producing output when they dry out. So, I would ASSUME that if there is no water or liquids in the cell, or outside air available, and if a cell is still able to produce an output without physical deterioration present, then that would at least be a starting point towards a non-galvanic long lasting cell.  The trick is getting some higher voltages and current levels out of that type of cell.  That is what I have been trying to do. I may only get a few mAs and a volt or so from each dry cells,  using just carbon and aluminum, but they are likely to last a long time, and have costed me,  zilch.
  Now some of the guys are making cells with upwards of 300 to 400 mA, but ... will those cells last?

I don't think we should go over the metal absolute value spread in voltage. If the separation is 1.2 volts then anything over that has to be galvanic and or electrolysis. This is what I have been noticing. Making a battery like this will depend on the ability of the cell to maintain it's voltage separation. If it can't it is weak at current and will lower the voltage faster but if it does maintain that separation then it can push harder and the voltage will be sustained at the value of the metals separation. What causes this separation I'm not understanding fully. It has to do with the chemical geometry and content as to weather galvanics are involved. The IB cells have a self healing quality to them because the fix a flat is included in the chemistry. The borax fixes the exposed aluminum and lays a oxidized layer to protect it fully in that spot. You can think of this process like when we break a leg. The fix is actually stronger then the original material. Now it's just a question of activating the break in a controlled rate and let it heal with a stronger connection. Eventually the cell get really strong but I think this is gonna take some exact calculating for the mixes to work as planned and yes I think there needs to be a protective layer to separate it from the environment from a water and oxygen barrage after it has completed the growing cycle.
