Hi I'm new here.
Just got 2 Li-Ion that I can't find out their specs.

1st one: unbranded from a DELL notebook.
Marking: SFIT4AB and a serial number for each one.
OBS: Look like the Sanyo (Panasonic) UR18650AA

2nd one: J.W.S. from a friend.
Marking: JWS 18650 4.2V 8800mAh (pretty strange)

IMG_7353.png


Didn't test both yet.
thank you.

The first one is most likely a Sanyo from the looks of it.
The J.W.S is false advertisin, largest capacity 18650 is aprox 3500-3600 mAh most likely it has capacity of 1000 mAh or less

These were pulled from a new florescent green 6v battery pack which was covered with Chinese writing. They weigh 42.2g.
(update) Charged with my Opus C3100 v2.2 at the standard 4.2v setting then discharged, they fell between 1731-1804 mAh. (Not 100% sure about these readings though because my charger has given some very erratic readings on previously tested batteries, as much as 300mAh difference on the same battery)

Hi everyone, this came out of a Koowheel electric scooter but I don't know the capacity.

LGGBM261865 are 2600mAh cells I have tested thousands of them almost all have been testing at 2600mAh or higher. The LG M26 series cells are all 2600mAh cells

Thanks for that. I have tested 3 cells so far, 2,527mAh, 2,490mAh and 2,493mAh. They are around 50m Ohms and charge to 4.1Vdc, but have been sitting on a shelf well over 6 months, so they have naturally degredated "naturally". But I will continue checking them all. I am using a SkyRC iMax B6AC V2 at the moment and wish to buy a 4 bay charger

50mOhms is that with the iMaxB6AC V2? I haven't read how they accurate they are? Is the imax a 4 wire IR tester?
All of mine came from 9bot battery packs (electric kick scooter). The bms had shut down on the packs, 90 % were good cells. The average IR was ~37mOhm So I bet your cells have a lower IR than the tester says. if you want to learn more about IR testing check out wolf https://secondlifestorage.com/index.php?search/64240/ he also tested loads of the LG M26 cells.

Yeah 46 to 44 ohms to be more precise. That link doesn't work for some reason

Couldn't find these in the database, some Panasonic CGR17670s which seem to be fairly rare, don't see many posts about them

Hi everyone, I m new here and I recently found this forum and it's been very helpful to identify my batteries that I removed from laptops packs. Today I came across this one, it's from an old Toshiba laptop, they are marked Sanyo Japan EKH, HR-4/3FAU, does anyone know any specs for this model. I can't find it. Thank you.
