We can not say enough good about these batteries !
Various lighting uses at home, defensive and for my buddy in Law Enforcement.
In a pinch most "dual" end power cords (with USB at other end for lighter charger) will charge your cellphone and these batteries with one cord, so less to carry with you !

My favorite 16340 battery

Love the micro USB charging on these batteries. They hold their charge well and I'm replacing all my batteries that I can with these in all my devices.

Good battery, but wish it were a little shorter

I like the USB option for charging this battery. The battery measures 34.9 mm long. There is a small red LED at the positive end that shows when charging and it turns green with fully charged. The battery tops out at 4.20V via the USB. Of course, the battery could be charged with an external charger too. I have RCRs from Olight and Nitecore that are 650 mAh and the Fenix at 700 mAh does last a little bit longer than those. I am satisfied with the purchase.

Good Battery with added Functionality
July 12, 2017
Seems to get the mAh stated. Fits all the lights I have tried it in. The charging port seems to charge the battery at a good speed. One thing to consider though is if you really need the built in port. It is very nice and works, but I adds a layer of "something to go wrong." Typically I carry a USB style portable charger (readily available on BatteryJunction) so these batteries only add redundancy to my system. However, they may be ideal for others to use in "non-rechargeable" light and make them rechargeable on the go.
