6. Mode: Each of the four buttons controls a slot. Within 5 seconds after power-on is put into the battery, the type of rechargeable battery can be selected by clicking the mode key of the corresponding slot. After 5 seconds, the type of rechargeable battery (e.g. 3.20V 3.80V) needs to be selected, the battery can be charged.
7. LCD: When the charger is connected to the power supply, the LCD display will be fully displayed for 3 seconds. If the battery is not placed in the charging tank, the LCD display null. 30 seconds after no operation, the display will be extinguished. When the battery is detected, the LCD displays the corresponding slot number and the battery type symbol (Li-ion-3.70V) flickers. If not, click the Mode key to select the type of battery to charge. If not, the battery will be charged in 5 seconds after entering the default recognition. At this time, the charge display percentage symbol flickers to indicate that the charging is going on, and the voltage, capacity and time are displayed. The percentage shows 100% when charging is completed and End is shown at the lower right.
