Great replacement for 2 CR123 Batteries
I have a couple of Quarks that are too tight a fit with 17650 batteries that these 16650 batteries drop right into and fit as well as a pair of CR123 primary batteries plus these have a longer run time. They also give a noticeably longer run time than a 17650 (which will fit in some of my Quark flashlights). These are Great batteries that fill a needed niche.

Great Li-Ion Battery Cell used with Streamlight Polytac
I bought this cell to use with my Streamlight Polytac, which replaced the two CR123 cells that it typically uses. I've used mine over several months and must say it has been fantastic! I just bought two more Orbtronic 16650 Li-Ion cells and I'm ready to put them to use.

Nothing but a great experience with this 16650 battery cell. I'm liking the the Orbtronic quality and price so much that I just purchased a 26650 battery cell for another flashlight.
