Hi Everyone
#21
Still have not started testing, but have over 1600 cells extracted now. I have nearly finished extracting all my cells, but there are more on the way.

I have not had much time recently so progress has been slow.
I have lost track a little, but I think there are about 1950 extracter cells now.
I can also get more batteries to extract, so I will concentrate on that while the source of batteries is there.
I have started on consistency testing of one of the zb206 testers and the results look good.
I am a big fan of the degradation testing performed by "generic" here so I have started doing something similar.
Generic has done many cycles and compared capacity loss of different types of cells.
I am doing something similar.
My test is with 2 cells that are the same type and came from the same recycled battery.
All cells in that battery had normal voltages when extracted.
I am using a single tp4056 and single zb206 for consistency.
So far almost 40 tests have been completed on these cells (20 cycles on each cell).
So far I have not seen any noticeable drop in capacity or change in IR.
What I have noticed is that capacity results seem to be lower when ambient temperature is lower. I might make another post in the testing section of the forum to discuss this.
