Green led on top shows full charge. Really convenient, and don’t seem to lose anything from having charger baked right into the battery.
Uses any usb charger with micro usb connector. More powerful the charger, faster it charges.

I think it is a simple but awesome concept having the charger port on the battery itself. They last forever between charging.

Typical Streamlight quality, have never received a bad one. The USB charger takes a little longer to charge, than a regular charger, but makes it very convenient.

Great protected battery for use with Streamlight (dual fuel) flashlights. I ordered this battery because I wanted the extended use of an 18650 battery, and wanted to try Streamlight's branded battery. Great life with extended use, so far!
