The Fenix ARB-L18-3500 is a high capacity 18650 Li-ion rechargeable with a protection circuit in the anode to help prevent short circuits, over charge/discharge and over heating. The battery also includes pressure relief vents which expel waste gas in the rare case of an internal short circuit preventing an explosion.
Good batteries, hold good charge.
Bought this replacement battery for my Fenix PD32. The 3500mAh battery exceeds my expectations and is far brighter than using CR123 batteries.
Its a great, powerful 18650, but damn it $30 for a single battery. At least I KNOW it will work 100% of the time
These are great batteries. I use them in my flashlights. I do not real care for the Micro-USB connector. I might if it was USB-C which can plug in either way and should charge faster. Since I'm taking out to charge much easier to have one sitting in chare ready to replace. No waiting around to put it back in after it finishes.
Good battery they last long time I ordered two extra ones..
These are good value for the monies. Long lasting and quick to recharge and mine came in the protective case which works great to keep them from rattling around in the storage bag. they are also not huge and heavy so you can take them with you if you might need extra
