A fairly low capacity and low current cell by todays standard.
The two cells tracks very nicely, the cells are not for high current there is a significant voltage drop at 5A (The cells are only rated for 4.2A).
Conclusion
These cells looks like good cells, but they are not up to the modern cells with neither capacity nor current (They will work perfectly in most flashlights).
