18650 Button-Top Rechargeable Lithium-ion Batteries [4-Pack]

Includes 2 Free Storage Cases with Purchase

High powered 18650 lithium flashlight batteries offering 3000mAh of reliable power. 18650 lithium-ion rechargeable batteries are unique and are packed with an amazingly amount of powerful energy. This provides dramatically increased longevity, low self-discharge, efficiency and optimized usage time. When you think of batteries, what might come to mind  is what you have seen in most in the store aisles. There is the widely used AA or AAA alkaline size batteries. However, alkaline batteries are old out-dated technology and cannot match the power of lithium-ion batteries. These 18650 lithium flashlight batteries deliver the power needed and offer up to 500 charging cycles.

These rechargeable lithium ion batteries are the best for using in LED flashlights, video doorbells, camping lanterns, indoor fans, portable radios, bluetooth speakers, work lights, motion lights, cordless power tools, solar yard lights and many other low drain devices. Lithium rechargeable batteries are also used in aerospace technologies applications (radio-controlled models, model aircraft, the Mars Curiosity rover, etc.). Theses batteries are protected with a small built-in electronic circuit which prevents overcharging and over-discharging.

NOTE: These batteries are NOT recommended for high-drain devices (i.e. Vaping Products).
