I voted other,
Cause i use VARTA-Professional.
These Cells have very low internal resistance, equal to Sanyo cells made in Japan.
VARTA-Professional are most likely made by Sanyo, as VARTA does not manufacture Batteries anymore.
I tested internal resistance with a GOOIT Gy518 battery analyzer.
AW used to test with the same device.
I'm sorry to tell, but all CR123's made in USA tested with higher internal resistance.
Sanyo cells made in China where on par with the us made cells, but all other cells made in China where inferior.
Beware of WF cells sold by DX and kaidomain, the worst i've ever measured.
