The calibration was unsuccessful for the second time.

The first time the exercise failed was also the first time I tried my hands at calibration back in Tally. When I realized the drop I was a tad confused. Did I miss out any steps or do something wrongly? Couldn't be. I was almost certain that the written instructions were religiously followed, especially when it was the first time I was doing it.

In any case, it was the biggest capacity index fall by far, nearly 5%. I even wrote to the site master and asked if such huge drops had been, perhaps, observed or known to happen to this PB model. Not that he heard of, he replied.

Second time I tried, it worked. I was almost delirious. Haha. It went up by 3%!

THEN this morning it happened, again. A dip to 4.142Ah, a 2.22% index drop.

*frustrated*
