299 total cells. These made it through the first charge and storage. Im not sure how many dead cells came out of this lot. I think I had less than 5 that self discharged. I'm glad I got rid of those, but the rest of them kept their voltage fairly well over 3-4 months of storage.

39% good cells.

# cells capacity range (mah) Average capacity for range.


(25). 2000-2099 Average 2050
(30). 2100-2199. Average 2150

Yeah whatever. these are learning cells that will go into the recycle bin after I'm done soldering on them. about 115 watt hours.

21% is pretty good. Hopefully the stats will stay that low :) Really nice capacities, too. Pretty good start.
