Step 8Last Chart
The final 5.7 hours before I stopped recording data.
The charged cell is still receiving a charge and the donor cell now has dropped to about .62 volts. The Joule Thief is still running.

you should have done this logging with the rechargeable battery starting out dead... this one just hovers at full charge... actually it appears to drop slightly in charge.

I discharged the battery into a load till its voltage was .9 volts. That is the recommended lowest you can go without damage to the cell. When a battery just sits there open circuit, the voltage will rapidly rise to a higher level, which it did. During charge the voltage will only rise slowly. The battery was no way fully charged. It was only a test to see if the circuit would raise the voltage and allow current to flow in a charging direction. Given enough time and dead batteries, the battery will charge.
