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.

AW ships the batteries in a small box.

These batteries are real flattop batteries, i.e. the plus pole might not connect when pressed against a flat surface. This will usual prevent the batteries from being used in series (because the minus pole is a flat surface on most batteries), but because the minus pole on these batteries has 3 bumps, they work fine in series applications.

These batteries are slightly lower in capacity, compare to some other batteries with the same cell, this might due to a different production batch or the cells being slightly older.

Conclusion

This battery uses a good cell, this secures many things:
The battery is one of the shorter 18650 batteries, but it is a flat top battery. The first can be an advantage, the last can be a disadvantage, depending on equipment.
All in all a very good battery.
