Performance is acceptable at least for one of the cell, the other cell has lower capacity.

Conclusion

The cell is not the very impressive, but as long as it is used one at a time it will work fine. Notice the size is correct CR123 size, not a few mm to long.
On this cell I have seen a UN38.3 test report, this shows that the cell is fairly safe.
