The cell used can be discharged down to 2.5 volt, in my test I only discharges to 2.8 volt, i.e. I do not measure the full capacity. But then, not all lights will be able to use the full capacity.
Note: The tested batteries are samples, on the production version the diameter might be slightly less.

Each chart has curves for two batteries, but these batteries are nearly identical in performance and the curves are on top of each other.

Conclusion

This battery uses a good cell, this secures many things:

The battery has a very high current limit (Like many other 3100 batteries), this does not mean it can sustain this high current.
All in all a very good battery.
