NITECORE NL1665R Battery

The NITECORE NL1665R is a 650mAh 16340 micro-USB rechargeable battery that's compatible with multiple 16340 flashlights, headlamps and other electronic powered devices. No charger is needed to recharge this battery, it's equipped with a built-in micro-USB port that allows users to charge the battery directly using any compatible USB power source. Yet, the battery does have the ability to recharge using a traditional charger providing multiple recharge options for users. The NL1665R is equivalent to 500 pairs of CR123 batteries and has a life span of over 500 recharge cycles, helping to reduce the cost of energy to users over time.

The battery boasts multiple external safety mechanisms like a microporous barrier to defend internal components and a pressure relief valve to protect against rapid temperature increases and explosions. A built-in high-performance protection circuit protects the battery from overcharging, over discharging and short-circuiting to prevent damage and prolong battery life.

Reviewer: Anonymous Person  
This was what their customer service responded with.

"Thank you. Please contact Surefire to ensure you get the correct battery, as the NL166R does not have the output necessary for the Surefire 123A batteries. "

3 of 5 Seem's like a good battery, except..... February 16, 2023
Reviewer: Michael B from Independence, MO United States  
Well built battery and charged in less than an hour.  The problem is that they are taller than a standard CR123.  I put them in my Surelight and they are a bit long in the tube and the button will not press.  The only way I can control the light at the high level is by screwing and unscrewing the end cap.  They fit in my TLR7 and work fine except turning the endcap that allows you to turn the light on/off, you have to turn is a bit past the click to get it to work.
