They worked great

Does not deliver the watts

Good design choice with the charger built in sadly a very poor performing battery.
I am getting about 30% of the expected run time with these batteries.
Buy many because you'll be swapping them often.

I have asked warranty to reach out to you to trouble shoot.

I love my Fenix headlamp as it is light, dependable, and bright. Highest recommendation.

Wish it were USB-C, but nonetheless reliable, fits the HM50R V2.0, convenient, and reliable.

Great product!

I really like the USB charger port. I don't have to keep a special dedicated charging unit on hand and if electricity isn't available, I can use a solar powered power bank or an adapter in my car. It's a tiny battery but provides good power.
