On the way home from a CO elk hunt. Headlamp worked great. No charges for 9 days of use. Red light is top notch, much brighter than competitors even on the lowest setting

It's always good to have a 2nd battery. Now I can keep going while the other battery is charging.

I haven't used these extensively but have been pleased so far. I have been using them on early morning hikes when getting ready and usually for first 30-hour of hike and charge has been good Will be using more this archery season.l be using more this archery season.

Just hope the two batteries I ordered are better than the ones I got with the head lamp

I wish I had a headlamp too try these batteries.
