Hi 507 PowerWall.

I've got one in front of me now ! Are yours pale blue or I think I have purple somewhere.
Mine came from cheap chinese generic laptop packs being sold in UK. where bms was faulty from new.
If you get more than 1800/1900 mAh I'll be very surprised. They never had more than 1900 when new. Normaly 1800
Typical rip off china packs being sold on e-bay
I join 4 together and use them in the 4 cell holders.

Hi.
Yes thats the one you have pictured.
They come in pale blue as well...not sure if the colour designates different capacity...mine were similar
I bought a job lot of returns from the retailer for little money, but stopped when they wouldn't supply cell data sheet.
Not sure where your located, but I gave up on laptop packs in UK and just buy 8 cell modem packs from BatteryHookup. .... https://batteryhookup.com/
You get as new cells testing 95 to 105% capacity with 1 in a thousand faulty and even paying 25% duty works out at 75p/ cell. to UK, making used laptop packs a non starter for me!!
If your testing with LiitoKala's then stick to just them....yes, they over read capacity, but that doesn't matter so much, what it will tell you
is the state of health of cells relative to each other. The key to a balanced powerwall is in the cell testing IMHO.

till later Steve

i wouldnt give up on these.
i would cycle some samples and see how much if any degedation occurs.
they might be fine.
or they might be junk.
i have nonames in use 5+ years that are fine.
and a few that are circling the drain after 10 cycles.

I found some references to "DSD" associated with Samsung - here's an example:
Reverse Polarity Samsung 30Q INR 18650 (DSD Charger)
DSD was a brand of li-ion charger many moons ago. It was a cheap charger. I should have given my brother a good charger right off the bat. I am most likely going to trash the batteries buy a new set and give him a good charger to alleviate any future issues. The light is a BLF A6 un-anodized.

So maybe this is a a cousin to aSamsung ICR18650-22F (e.g.2200mah) cell that carries this DSD brand instead of 22F- e.g. kind of an off-brand part of the Samsung family?

My first charge with Liitokala shows <50 IR... I know that this reading is an average... not like the YR1030 reading of IR but is promising
I got 6 of them... two weight =45gr the rest 41gr.... Odd
Are resting to be NOR tested in few days.. I will post results (and are fairly new, taken from a OEM laptop battery replacement ) never used in the computer
