Electrically OK, but won't fit due to poor manufacturing practice.
January 24, 2015
Ordered two batteries, one fits in my light fine but the other does not. Upon closer inspection, the plate on the negative side is skewed from the rest of the battery. When the battery was assembled, their fixture failed to keep the plate in the proper position when it was (I assume) soldered on.
Pros:
Electrically, the other battery I received does what it should do. The low voltage cutoff works as designed, so plan accordingly as you will suddenly have no light at some point.

Too Long
January 9, 2015
I bought this for an Olight S10R and it's too long. The end cap will not screw on all the way (no electrical contact) when using this battery. It wouldn't work in my JetBeam RRT01 either.

I would recommend this item to a friend.

Size different from other 16340's
November 27, 2014
Capacity is good. Longer than other 16340's to achieve the capacity. Will not fit all devices.
Pros:
mAH
Cons:
Size longer.
