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
(38). 2200-2299. Average 2250

(1). 2400-2499 Average 2435
(8). 2500-2799. Average 2650

117 total, 260.135 amp hours @ 3.7 Volts = 962 Watt hours. Going in my power wall.
Average capacity 2223 Mah

40% OK cells

(11) 1000-1099
(22) 1100-1199
(45) 1200-1499

120 total cells, Not sure, don't care. I will find a project for these. about 617 watt hours.

21% crap cells

(62) 50-999

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.
