Longer battery time in my headlamp. Not to worry about being in the dark. Highely recommended.

Awesome!

I love the batteries, I bought cheap ones at first but they couldn't even make it thru the day, but then I bought yours.. it's for a nite core head lamp, and then I got the charger for the batteries as well, I've only used one battery so far, just exchanged it for a charged one af wrk yesterday.. they last so much longer, definitely worth the extra money!!! They take awhile to charge but it's so worth it!
