A 18500 battery, the 1 mm more thickness compared to a 17500, do increase the capacity significantly.











The curves looks very good, as long as I do not overload the battery.















Conclusion

The battery looks very good when stating inside the rating, but it can deliver considerable more current.
A usual this type of battery gets an acceptable rating.
