Reviews
Powerful, protected CR123A at a good price
"Great fit in all my flashlights. A high quality protected battery with long lifespan. Works as advertised. . ."
Electrically OK, but won't fit due to poor manufacturing practice.
"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."
Too Long
"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."
Size different from other 16340's
"Capacity is good. Longer than other 16340's to achieve the capacity. Will not fit all devices."
