3. Description of buttons

The charger has four buttons, the mode button, channel 1-2 data tracking buttons, channel 3-4 data tracking buttons , and current button. The four buttons have the function of lighting LCD backlight at the same time, which is sile and convenient to use;

1) Mode button: mode selection; including charge charging mode and capacity test mode; under normal circumstances, long pressing mode button switch between charge mode and capacity test mode: first, press 1-2 and 3-4 keys to select channel, then long press mode to change work mode, press current key to change current, if no action for 8 seconds, it will enter into working state, so easy to operate;

2) 1-2 channel key: corresponding to channel 1 and channel 2; continuously press the key to select and view the data of channel 1 and channel 2 in turn;

3) Channel 3-4 button: corresponding to channel 3 and channel 4; press the key continuously to select and view the data of channel 3 and channel 4 in turn;

4) Current button: current selection; Li- ion:500mA/1000mA Ni MH / Ni Cd: 500mA; long press this key can control the LCD screen to display normally;

The charger can press the corresponding function button to change the independent charging or different current selection, as well as the mixed charging of different batteries. Under the working state, you can lightly press the (1-2, 3-4) key points to view the corresponding channel current (MA) / capacity (MAH) / voltage (V) / time (H) and other data reference values.

4. Mode operation description:

When the charger is connected to the power supply, the LCD screen of the charger will be fully illuminated and fully displayed in a moment, and it will be ready in 3S. If no battery is not inserted, it will display "null"; if it is a bad battery, or if the battery is reversed, it will display "err"; when the battery is fully charged, it will display”end” and “100%”;

1) CHARGE MODE

1.1 when the charger is connected to the power supply and inserted with battery, the system will automatically enter charge mode and will default charging current as 500mA. Within 8s and before the charger starts to work, you can select the charge current of 500mA or 1000mA. If no more action within 8s, the selected current will be locked for charging while other functions will be locked. If you need to change, you can long press the mode button to re-select;

1.2 in charge mode, when the "charge" is flashing in the LCD, press 1-2 and 3-4 channel buttons to select the battery channel, then press the current button to select the charge current. After selection, if no action for 8s, it will enter the charging state. Pay attention to selected charging current which should be according to the capacity of the battery. If fast charging is not required, 500mA charging is recommended, which is the safest;

1.3 in charging mode, you can view the parameters such as capacity(mAh) / charging time (h) / charging current (mA) / battery voltage (V) of each channel by lightly pressing the channel button 1-2 and 3-4. After the battery is fully charged, "end" will be displayed;

(Note: when charging with 1000mA current, only two channels of the 4 can be inserted with batteries, only for lithium-ion battery. If more than two channels are inserted with batteries, the system will automatically reduce the charging current from 1000mA to 500mA.)

2) CAPACITY TEST MODE

2) Test (capacity detection mode)

In the test mode, The process will be firstly fully charged, secondly fully discharged, while the discharge capacity and other parameters are recorded finally the battery is automatically fully recharged(the charging capacity will be not recorded). The LCD display retains the discharge capacity and other parameters for the discharge stage. The detailed steps are shown in the following figure:

Enter TEST mode, select the charge current, starting charging, discharging then pre-charging, showing “END”

2.1 long press mode in any state to re-enter test mode;

2.2 after entering the test mode, 500mA or 1000mA charging current can be selected within 8s. if no setting is done within 8 s, the system will automatically lock the 500mA current(the current at this time is the default by the system). (Note: Ni-MH(Cd) batteries can be charged only at fixed 500mA current)

2.3 when the battery is fully charged for the first time, the system will automatically switch to discharge, and the discharge current is fixed at 500mA. After fully discharged, system will record the discharge data of capacity, voltage, time and so on.

2.4 when the battery is fully discharged, the system will automatically switch to fully pre-charging after which the system will not record the charging capacity data, but the discharge stage capacity. The “end” image will flash it is fully pre-charged. Finally, the system will display “end” and “100%” and stop charging.

(Note: when charging with 1000mA current, only two channels can be charged and only lithium-ion battery can be charged. If more than two channels are used, the system will automatically reduce the charging current from 1000mA to 500mA for charging; the discharge current is fixed at 500mA.)

5. USB power bank 5V output

5.1 USB is only used as 5V mobile output, and the output current is 1000mA;
