I have many 18650's from different manufacturers. Nitecore is on top of my list along with Olight. Has the actual capacity as advertised. Works well in my torches & other devices. Can simply charge the battery from the micro USB port on the battery. This is very convenient if you don't have a charger around & just a micro USB cable & power source. ie, DC USB car adapter or power bank.

The are just great batteries. Long lasting charge. Easiest to just buy directly as you know you are getting the real deal and the prices are close enough to skip the third party seller.
I used it on a deep backpacking trip.I had a Goal Zero Nomad 7.The new built in micro usb port is the greatest.I can top off the battery without having to lug spent battery.WARNING ... the battery is slightly wider that the standard ... tight fit on Nitecore SRT7
These batteries exceed the length specified by 18650 and will not work all devices.
It's pretty cool to have a built in charger. Not at all necessary but is a nice upgrade for (low current draw) lights which don't have a built in charger.It's a bit disappointing that the button too gets so hot, hence the 4 stars. (Be careful what materials the battery is near while charging)Though it does have a red light for charging and a green light for charges which is pretty smart.
I highly recommend Nitecore products. I currently own 3 flashlights, 1 headlamp and several batteriesThey are all fantastic.
It works great and I love that there is no additional charger needed. For this specific battery the charger is built into the battery. All you will need is a super common charge cord (mini USB i think) and you can charge the battery.
