Notes on Polarity and Connection Challenges
A critical observation was the polarity of the voltage output. In one test, the positive side was inside, and the polarity "switched" in the other, highlighting the importance of correct orientation when measuring these cells. Achieving a stable connection proved somewhat challenging, with the testers needing to hold the probes in place carefully and adjust their positioning—specifically favoring the bottom connections where contact was better.
