Good batteries, hold good charge.

Mike Parmelee
Extremely Bright

Bought this replacement battery for my Fenix PD32. The 3500mAh battery exceeds my expectations and is far brighter than using CR123 batteries.

Nathan Ramirez
Paying for quality

Its a great, powerful 18650, but damn it $30 for a single battery. At least I KNOW it will work 100% of the time

Excellent Batteries

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 product


Good battery they last long time I ordered two extra ones..

good value for the monies

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
