This is a fairly new 35E cell (Supposed to be 2020) from Samsung. It is a high capacity cell.

The two cells tracks fairly well, the cell can handle the rated 8A.

[size=+3]Conclusion[/size]

This is a good cell, but performance is lower than the one I tested some years ago (This may be because this cell was produced some time ago).



[size=+3]Notes and links[/size]

The batteries was supplied by reader for review.

How is the test done and how to read the charts
How is a protected LiIon battery constructed
More about button top and flat top batteries
Graphical comparison to 18650 and other batteries
Table with all tested LiIon batteries

A bit clearer summery would be nice. Either cell do anything odd or note worthy? The difference between tests, now and past, within manufacturing tolerances or the testing margin of error?

Some of the graphs are very info dense, any chance of larger scale, fewer test results per graph or maybe averaging the cells as one track; if they performed closely enough to each other? Also depending on the readers monitor settings some of the tracks maybe hard to read.

Great testing and lots of good info here but not everyone will take the time needed to review and benefit from your work. Thanks for the testing and post

I cannot say if the cell is within tolerances, because I do not test the same way Samsung do.
If you want a chart with fewer curves and to compare to other cells, follow the link to the comparator.

That IS a data base. Been at this awhile have ya. They should make it a reference link on the board.
