I would recommend this item to a friend.

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.
Accurate rating
