Hopefully it is genuine because there are many counterfeit Ultrafire
torches with fake Cree LEDs and fakes 18650 cells.

How do you fake a 18650 cell? Lots make them.

Lots of manufacturers make cells called Ultrafire 18650 but few are
made by Ultrafire.

There are so many fakes that you can't be sure of getting genuine
branded 18650s even from a reputable retailer. YouTube has plenty of
warning videos.

Maybe pinch a tesla and use its batteries?
