Fasten the battery on the activate plate, if voltage lower than 2.5v, digital and indicator will not be display due to lack of power supply, and if voltage higher than 2.5v, it will be display normal.
Please adjust appropriate output voltage according to the display of voltage, the higher the voltage, the greater the current, When the right display of voltage lower than or equal to 3v, then please adjust output voltage to below 3.5v, then charging it about 1 -2 mins by trickle charging. When turning on the power, the right will display current charger voltage.
If voltage is more than 3.6v, you can use more than 4v voltage to charging it, the left will display current, the right will display the charge voltage.
If you want a quick charge, please note the left current display when adjusting voltage, the current maximun should not exceed 2A, otherwise it will be auto protected.
