Great battery for your streamlight product
Streamlight is a great product. I use my headlamp for hunting and it lasts all night. Charge off the headlamp itself or the battery itself has a usb-c charger in it. GREAT idea. Works great fits right and does not weigh too much. Worth the price and investment for your product

Holds a charge very well and lasts a long time, even if using flashlight at highest brightness. Love the USB recharging capability.

Backup just in case
Bought this as a backup in case I forget to charge the main battery. Size and quality are great. The flash light for it is amazing and long lasting.

Its really nice to have a backup battery when it is cold.
Carry a backup. Batteries don't last as long when its cold outside. You can't find these just anywhere and should order them online before you need them. Really nice how easy it is to recharge either in an outlet or in a vehicle with a USB-C cord, or even with solar.

Replacement battery
had to replace my older rechargeable battery, holds a charge for a long time and provides flashlight with enough power to give a very bright light.
