Magnetman2010’s Duracell AA experiment

This is an attempt to replicate an experiment by Magnetman2010 here at YouTube. He replicated my led ‘Penny’ oscillator years ago and in 2016 hooked it up to AA Duracell rechargeable battery. He then just left it to run 24/7. It is still running 24/7 today with usable light. I decided to set up my own experiment and study what is happening.
Here is my video from long ago on how to build the ‘Penny’ oscillator:

Here is Magnetman2010’s replication of the device back in 2011. He didn’t put the Duracell on it until 2016.
