Im dismantling and laptop and I harvested 6 cells from the battery pack.
This laptop was in heavy use for about 3 years and then it was sitting in the shelf for about 10 years (yes, no joke here).
A few weeks ago when I switched it on, a warning showed up that the battery pack needs replacing. Obviously Im not going to replace anything, I just dismantled it .
These cells are of the same size as 18650 cells, however, there is no mention whatsoever about 18650 on the wrapping. I decided to peel the wrapping off in order to figure out if there was any more info under the wrapping but guess what? No, the info on the wrapping is the same as in the cell itself.
There is a C written in the middle of the cell and then some sort of reference JKLFK47 and then 136988, also there is K45A engraved on the wrapping.
From the cell data base, in this forum, judging by the colour and the green ring at the top, it seems to be a Sanyo UR18650FK.
However, as I said above, there is no mention on the cell about Sanyo UR18650FK
I wonder if I can do a capacity test on these cells using my LiitoKala Lii-500 because there is no mention about 18650 on the cell itself.
