Unknown ASO/SZN Cell Specifications
(02-13-2019, 11:41 PM)paulz Wrote: 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


I have ASO GI4I051EJ1 814808 (purple-white ring)

i bought them as 2600mAh high drain 20A.
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:

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."

Also found some of 12 these GE20106EW in a notebook battery. The spec on the notebook pack say its about 2200mah. The IR looks very good and i will post the cap. results later

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

Cell count as of 7/19/2019
54 Cells >2000mAh, >80% Rem. Cap., 14 day resting voltage >2.12V
100 Cells of Everything Else

Aiming for 2400 tested cells a year with one charger
I found a few of these in laptop batteries. An initial capacity test with my Opus BT-C3100 yields roughly 2100mAh consistently.
