This is a low capacity, low current cell. Tmart has this cell in four configurations, this is the unprotected button top.

The cell can deliver up to 5A before it looses capacity. The curves here looks good when staying below 5A, but as can be seen with the flat top version there is some variation between cells.

There is no problem with temperature at 5A

These two cells do not match neary as fine as above. The current handling is the same.

No temperature problem here.

Conclusion
These batteries do not win on capacity or high current, but they can easily drive a normal single cell flashlight.
I would have liked a bit better matching between the cells, but when used one at a time it is not a problem.

Oops, thanks. I copied my internal link, instead of the public one. It is fixed now.
