No more buying expensive batteries. The Ready Up Gear USB Rechargeable 18650 batteries replace traditional and expensive CR123A batteries.
These batteries put out 3.6V to maximize the brightness output of your flashlight. In addition, 18650 batteries are commonly used in cameras, LED clocks, and portable speakers and fans. The 18650 name is based on their nominal size of 18 mm diameter by 65 mm length.
*Please note that while Almost ALL flashlights that are powered by 2x CR123a battery should also accept a 18650, there are exceptions. Some flashlights are unable to accept the increased voltage output and using a 18650 could damage your light in those circumstances. The user is responsible to verify the compatibility of the light. Generally, flashlights that boast of being “Dual Fuel” can be used with a 18650 battery.
The RUG 18650 Lithium-Ion Batteries can be charged via the onboard Micro USB port or by a traditional charger as well. (Charger and/or USB cable not included)

How long they run per charge will depend on what the battery is powering.
