Bulk batteries purchase
October 15, 2015
I bought these batteries to serve as "disposables" in my 18650-only lights, should there be an extended power outage where I couldn't recharge. All 10 of these charged correctly, held their charge correctly, and cycled fine. These now sit in holders, charged and ready to go for when the lights go out!
Pros:
Inexpensive, serve their purpose as "disposable" cells.

Good fit for tight lights, accurate rating
March 19, 2015
Fits all my lights, even those that are fairly tight on other cells. I don't have the test equipment to fully measure output, but runtime on lights is in line with the 2400 mah rating. Unlike some other cells, no overblown rating and short runtimes here. Also no duds in an order of 6 cells.
Pros:
Accurate rating
