These 16340 batteries are short for protected batteries, i.e. they are very close to 34 mm long (Same size as CR123 batteries). This battery can only replace a CR123 battery in equipment designed for LiIon, because it has higher voltage than a CR123 battery.

The capacity is slightly below rated value, but that is very common for 16340 batteries. The batteries do not track perfectly.

The protection is at 5.6 ampere, this is a bit high in my opinion.

Conclusion

This battery has a size very close to CR123 batteries and a construction with a metal plate at the bottom, both are good details. But that the battery uses a cell from an unspecified supplier is a minus and I would also have liked the discharge curves being closer.
I will call this battery acceptable.
