I just found some.. going to test on opus and treat it as a 4.35v battery. Will test one on 4.2 and then 4.35. I saw some specs that makes me believe these are LiHV cells.

I would make completely sure of this. Charging to 4.35v does not yield a huge gain in capacity, and if the cell is not LiHV it may explode.

ASO GK2K121EP 811930 SZN

6 cells recovered from an unused ML:4710 Acer battery pack 4400mAh 49Wh (generic NON-branded)

Wrapper = Mauve/Pale Purple
Insulator = Translucent /White

All cells seem to charge to 4.2v OK and discharge to 3.00v

These are 2000mAh rated. Do not trust what the laptop battery pack label says. I have opened up hundreds of generic packs now, and I can confidently say that 0% of them were labeled correctly; all of them were "hopelessly optomistic" and had a higher rating on their label than the cells they used inside.

Also, these ASO cells are definitely not high drain cells. I don't have a data sheet, but I wouldn't push them past 2C.

Lastly, these are very good generic cells. I'm doing a longevity test on these and you can follow my progress here:https://secondlifestorage.com/t-Generic-Cells-Are-they-any-good

Mike, can you change these from "Unknown" to "ASO" as the brand? I originally thought these were missing from the cell database, but they were mislabeled "Unknown."​

Got a Purple wrapper with White insulator ring, Model number GG20304EG, tested at 2154mAH on 1000mAh discharge on an Opus.

I found a few of these in laptop batteries. An initial capacity test with my Opus BT-C3100 yields roughly 2100mAh consistently.

(Ignore the handwriting at the bottom, that's my personal serial number system)

the folks that figure these are 2600mah cells from the specs are wrong.
these are 2000-2200mah new.
aftermarket pack mfrs lie about their packs capacity.
this is why many such packs are at 75-80% wear level after the first cycle.
they clone the bms data and the chip calculates the capacity compared to the design capacity.

Thought I'd add this serial to the list, will hopefully test in about a weeks time (if my budget supplies an imax b6).

Hello, I found these but I don't have any data about it, I suppose they will be 3.7v Li-Ion but I don't know if it is true and how many milliamps they are .... Do you know them?
