2 Pack Rechargeable Battery 18650 Li-ion 2000mAh 3.7V
The Lithium Ion 18650 Li-ion 2000mAh 3.7V rechargeable battery is used on most flashlights as well as our 50mW Kaleidoscope Laser Pointer laser pointer that we offer here. Having extra batteries for your flashlights or our 50mW Kaleidoscope Laser Pointer are a great solution to keeping your light shining bright.
When one set of batteries starts to run low, replace them with an extra set of Lithium Ion 18650 batteries and put the dead batteries on the charger to charge --you’ll never be without power in your flashlight or laser pointer.
