Glow-in-the-dark bleach body has a metal ring, it is twisted from there, the battery is inserted in it, generally the iron needle is inserted towards the end of the bleach, and then the electronic bleach will be bright, and the battery will be installed after use.
Glow-in-the-dark drifter batteries can generally only be used for more than 30 hours, and can be charged to continue to use. The first is to determine the positive and negative terminals of the battery, which is not difficult, because it is marked on the battery. Find a working idle mobile phone charger (output voltage is about 3.7 volts DC can be) cut the plug connected to the phone and use a multimeter to determine the positive and negative terminals of the output wire. Connect each end of a plastic clothespin, and mark the positive and negative poles. When charging, as long as the luminous drift battery according to polarity (positive to positive to negative) sandwicked between the plastic clothespin can be charged, it should be noted that because some luminous drift batteries are not rechargeable batteries, pay attention to the charging time, can not be overcharged.
