PKCell Lithium-ion 18650 21700 Battery 3.7V - TRUE RATED 18650 2200mAh 3000mAh 3350mAh 4500mAh Rechargeable Battery for Power Bank, Flashlight, Mini Fan

A growing number of electronic devices use 18650 Li-Ion batteries. Flashlights are using the 18650 battery to power the current hungry LED bulbs, and to provide longer standby time when not in use. Previous rechargeable battery flashlights had to be left on the charger almost all the time so that it would be ready to use in a moment's notice. This 18650 Li-Ion battery can be left off the charger for months and still have over 90% of its charge. This enables you to charge an extra battery and have it ready to use in your flashlight in case you are going to be away from electricity for a long period of time or you forget to charge your original battery.
