[4000 mAh] My Fenix flashlight was discontinued and I had to scramble to replace a unique, difficult to find battery. My original battery (no longer made) did not have a charging port. Despite the fact that this one does, it fits the purpose and brings new life to an old dependable flashlight. I am not able to charge it in the flashlight but can use the cable from the original unit, thus saving having to buy a new cable. 5

[0.19 lb] Exactly what I needed! Charged up as expected and works perfectly in my equipment! 5

[Li-Ion] The batteries came as described, good pricing. 5

[Li-Ion] I've used these for years, and find them reliable. They hold the charge well and deliver plenty of power. 5

[Li-Ion] Good to have an extra pair. While one pair is in the charger I have a working flash light (Fenix LR35R). I am a little new to this particular battery type, I've been using 18650s in other Fenix lights and battery banks with narry a problem. Fenix lights put out lumens and well lit up road signs in pitch blackness (at midnight) from the far side of the road in Yellowstone. 5

[Li-Ion] The two batteries that I ordered for my o light warrior pro arrived in a timely manner and worked great. I've always been happy and satisfied with BH photo service and delivery times. I've been using them to buy equipment for probably the last 30 years and never been disappointed. 5

[3.6 V] Fenix store was out of stock, I needed an extra for a trip. Thanks for being there! 5

[3.6 V] I have many many of these and they work well in the Olight I use them. Like all lithium cells, they eventually lose their capacity as the number of charge cycles increases, but it takes a while for this to happen and a replacement is inexpensive. The USB charging feature works well -- I use this almost as often as I charge these in a stand alone charger. 5
