Please note that both of these cells "failed." The one that says it failed is because I was testing it to 100% of its claimed capacity. The one that "passed" only had to pass 95% of its rated capacity. The green vertical line is my passing test criteria of 95% claimed capacity. So in that sense both cells passed. Also note that this is really two different tests for the same cell. Batt1 and B1 are both cell #1. The difference is that one test was at the 5 hour rate of 600mA, the green lines, and the other, the red lines, was at the 10 hour rate of 300mA. |
