This works as it says

### ⭐⭐⭐⭐⭐ Great charger.
*by J***C on May 18, 2025*

Timing couldn't be any better. Needed to charge my LED flashlight battery, due to a faulty charge circuit in the flashlight. Now I have spare batteries for my flashlight. Accept different sized rechargeable batteries to.

### ⭐⭐⭐⭐ Great deal, battery doesn't last as it long as it should
*by D***  on June 4, 2024*

I bought these as a replacement for my Fenix 3500mAh. These are supposed to be 9900mAh which I didn't really expect. I installed it in my caving light and turned the light on to test it. It did great for 7 hours and then dimmed to unacceptable levels. My original Fenix if good for 10+ hours. I am happy with the purchase and would have given them 5 stars of they had held up longer. I would recommend them and would purchase them again.
