special Reminder: lithium battery is used for Flashlight. The new battery is charged first and then used. Lithium battery must not be overcharged or overdischarged. It will stop charging after the battery is full. Please charge it immediately when the battery is insufficient, otherwise, lithium batteries are easily damaged or even scrapped. (The full voltage should not be higher than 4.35V, and the discharge voltage should not be lower than 2.75V)

lithium batteries are limited in number of times, generally about 800 times. Each plug-in is equivalent to charging the battery once. Each charge shortens its life once.
