The Nitecore F1 is a finger sized battery charger with many functions including: Standard Charging, Intelligent Charging, Power Bank Function and Battery Activation. The Nitecore F1 is capable of activating depleted Li-ion batteries with protective circuit. After battery installation, F1 will test and activate the battery before charging. When a battery is detected as damaged, the LED goes off, and the user should stop charging. Such damaged battery cannot be activated by F1. NOTE: Nitecore does not recommend charging 0V (depleted) unprotected Li-ion batteries with F1 and doing so can result in battery fire or explosion. Power Tips 1. When a battery is installed inside F1€™s charging slot, its power indicators will blink to indicate the
