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
(15).    2300-2399 Average 2350
(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
(42) 1500-1999

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 Smile Really nice capacities, too. Pretty good start.
