Another mystery generic cell from a generic 6-cell laptop pack:

Capacity tested 584mAH/181mOhm and 558mAH/163mOhm, so not sure what the original capacity was since this must be very heavily ddegraded. I'll update if I ever find the cell info, but after a quick search of the model number(s) (FC14-HE-L097) on Google and Alibaba, no hits.
Lishen LR1865EH

I guess i was not allowed to add pictures to the cell database so ill post here I have some LGDDBHE21865 they are 2500mah and came from a ryobi 40v 5Ah

Note: We need pictures to create a database entry. You can upload them where it says "Drop files here to upload" in the full post editor or new thread editor.
Found a cell I could not find in the database. The green one listed for ICR18650NH does not match. 

Unknown brand from a laptop. Capacity rated in Wh which is unusual. 

Cells tested: 4087
Average capacity: 2082 mAh
Left to process: 165 kg
Haven't found these in the database, so here are some photos

1) LN INR18650

Capacity test showed 2022 (discharge with 500 mAh).

2) DSD ICR18650T

Capacity test showed 1922 (discharge with 500 mAh).

3) SZNS 18650 3,7V 7,4Wh

18650 3.7V 7.4Wh SZNS
Rated Capacity - 2000mah

Rated Voltage - 3.7V

Cut-off Discharge Voltage - 2.75V

Charge Upper Limit Voltage - 4.20±0.05V

Charging Time(Std) - 4.0hours

Standard Charging Circuit - 0.2C A

Charging Circuit - 0.5C A

Standard Discharging Circuit - 0.2C A

Fast Discharging Current - 0.5C A

Max Discharging Current - 2C A

Weight- about 50g
Height - 65mm

Capacity test showed 2185 (discharge with 500 mAh).

I have found those in a different color. Here are some pictures

Capacity test showed ~2200 (discharge with 500 mAh).
Here are some more cells, that I have found in batteries for scooters. Most probably these are from some Chinese manufacturers. Battery packs were 10s2p 4-4,4Ah, so cells should be at around 2000-2200 mAh (originally).

1) HL 18650-AH00

2) ICR 18650MR

3) INR 18650HP

4) INR18650HE

And some more cells, that I do not see in the database

1) SZNS 18650MP

2) Sanyo UR18650AA
I did not find these on the database it is EVE brand and 2Ah they came from a ryobi 40v 4Ah battery
