4, lithium battery standard 3.6 3.7 V voltage, after full charge voltage of 4.2 V, it finished when the electric voltage of 2.75 V.
5, do not use the advice is full of electricity saving for a long time, and charge once every six months.
6, the battery has no memory, can at any time in charge at any time.
7, in use process, the torch brightness clearly please turn off the flashlight when dimmed, take out the battery to start charging, prevent discharge.
8, -20 degrees above the lowest temperature , the highest temperature is 50 degrees.
