Jones! You have posted reference to 'Splitting the Positive' as you were able to find on the great www, which is sparse at best for some reason and what is available is far from what I was shown decades ago. In my case I was able to observe a system in which two primary cells were connected as ( - to - ) and the working terminals were the two positives. (Similar to Aarons) The old technology of relay (contact) switching was employed in switching a tank circuit ( L and C )across the two + terminals. What I saw was an increase in charge in one battery and a decrease in the other.
Knowing what I know today, I ask how this could have been possible, how did an oscillation determine which battery to drain and which one to charge. (There was not rectification in the circuit). It only consisted of a relay switching a tank circuit into and out of connection of the two + terminals. My first thoughts were on a voltage generation caused by a difference in the contact metals, which could act as a diode, but common sense would say this voltage would be so low it could not charge a primary cell. Another idea was that there was in some way an induction from the relay coil that was producing the charge. Over time, one battery did obtain additional charge and one lost charge in the same proportion, so it was not a leveling of charge. This is what I have mentioned in communications on 'splitting the positive' and it is indeed different from what seems to be available on the web. My memory can be classed as much as folk lore as any other. To this day I wish I had possessed the foresight to look into this further.
