The battery is a slightly short versions of a 18500 battery and because it is IMR it does not have protection, but can deliver a lot of current.

Conclusion

The battery has very good performance at high currents, but as usual with high current batteries the capacity is on the low side.
It will rate it as an acceptable battery.
