Works great. – UltraFire Protected 18650 3.7V 2400mAh Lithium Batteries (2-Pack Grey) Reviews

Involvement:General (knows how to use it) - Ownership:1 week to 1 month

Pros:
These work fine and do their purpose. I've used them in my WF-501B R2 flashlight. They are the cheapest 18650 protected batteries with 2400mAh. They've held up fine, and last a while (I don't use my flashlight too much, and I charge the batteries much more than needed so, I don't know a runtime).
Cons:
They're probably not REALLY 2400mAh. Also, since they're protected, they don't fit in ALL flashlights.
Other:
I have no way of testing the mAh.
Bottomline:
I was skeptical about getting them since there were no reviews and it's labeled "GREY: on DX, but... they ended up being fine. If you were unsure about getting it, I hope this review shows you they DO work fine.
