Brilliant Battery

A very easy to change battery. Charges with a small usb connection that I already had from an old phone. Battery features a charging indicator light so you know when it’s done. Had ~18 hours of use from my Fenix headlamp on a recent November (mostly dark) camping trip to the Scottish highlands. Pretty good value. Only had it for a few weeks. Hope that it lasts for many charges to come.
