## Customer Reviews

### ⭐⭐⭐⭐⭐ Works well in place of 2. Cr 123 batteries
*by T***S on February 16, 2025*

Goold substitute for Cr 123 batteries and they are rechargeable. Seem to last a long time. Would buy again/

### ⭐⭐⭐⭐⭐ Does a great job in my Arisaka lights
*by J***. on December 28, 2024*

They put out all the power my Arisaka lights can output, and they're rechargeable. Gone are the days of blowing through expensive CR123's after one evening of training. Expensive, but solid and go to go.
