3. Do not use other power adapter;

4. Chargers discharge may be hot, be careful not to burn;

5. Stop use, unplug the power, removing the battery;

6. it can only be used in normal room.

7. This product test data for reference only, please refer professional equipment.

Second, characteristics

1.4 kinds of charging current regulator (300mA / 500mA / 700mA / 1000mA);

2. Can different specifications (18650/26650 ...... / AA / AAA) in the battery charger;

3. The charger preclude the use of a separate screen LCD display, voltage (V) Current (mA) 

Time (h) Capacity (mAh) resistance (mR) parameters, E glance...;

Under 4. CHARGE mode, 4 channel work independently, you can select different charging current for 

charging and Hunchong lithium-ion batteries and nickel-metal hydride batteries.

Under 5. FAST TEST mode, 4 channels can quickly detect the battery capacity, regardless of the 

lithium-ion batteries and nickel-hydrogen batteries, are working independently. Rapid detection 

of battery capacity process (1 discharge, 2 full) by the two step

6. NOR TEST mode, the battery capacity is normally detected by the three step process (1 first 

charged, then discharged 2 and 3 refill), the detection process of the battery capacity;

7.CHARGE and FAST TEST / NOR TEST 3 modes can work simultaneously; independent set charge / 

fast capacity detection / normal capacity detection;

8. A variety of protection functions: overcharge and over discharge, short circuit, temperature, 

0V voltage activation function, (- ΔV & 0ΔV), 1.65V-2.2V can not be charged, intelligent 

recognition bad battery and reverse-battery detection protection.

9. with standard 5V / 1000 mA USB output: from 1 to 4 lithium batteries lithium batteries USB 

output is completed, the product can not be nickel-metal hydride battery with USB output.

10. with a dedicated power adapter: DC Input voltage: 12V / 2A.

Third, the description of the keys

1.The charger has six buttons, mode selection key (MODE), the current selection key (CURREN),

and view the data independently selected key (1234), the use of simple and convenient;

2. Hold down the MODE key in any case and held for 3 seconds to change the CHARGE (charge) mode 

or FAST TEST, NOR TEST (capacity test) mode, then tap again corresponding to the function keys 

can be changed within 8 seconds, to current, independent, Hunchong, capacity test, the selected 

function after 8 seconds into the working state, in working condition can tap the (1234) key 

to view the current (mA) / capacity (mAh) / voltage (V) / time ( h) / resistance (mr) data 


Fourth, the mode Description:

CHARGE (charging mode)

1.When the power is turned charger, the charger all instant full brightness LCD screen, if the

battery is not placed in the display Null, if it is a bad battery will also be displayed

into the Null;

2. Insert the batteries power charger, the charger in three seconds or so to measure the internal 

resistance of the battery, after which the system automatically enters charge mode (CHARGE), the 

charger automatically default charging current is "500mA, in 8 seconds within the current 

selection by key (CURREN) select 300mA, 500mA, 700mA, 1000mA current charging system lock current

that you select will be charged in eight seconds, if within 8 seconds, did not make the set, 

then the system automatically defaults to 500mA charging current, current and other functions at 

this time will not be changed, if necessary change, need to change the mode button press from the 


3. In the charge mode (CHARGE), within 8 seconds to change any of independent charging or 

different current selection, as well as different battery Hunchong. make a simple, 8 seconds tap 

the corresponding button battery 1234, press mode button to change the mode, press the current 

key to changing the current, independent, Hunchong, capacity detection function, selected after 8 

seconds into the working state, attention according to the battery capacity size to select the 

charge current, if not fast charge, we recommend charging 500mA, this is the safest;

4. charging mode, by tapping the keys you can switch to view the 1234 charge capacity (mAh) / 

charging time (h) / battery internal resistance (mR) / charging current (mA), voltage (V) 5 kinds 

of units, the battery is fully charged After the show, (end of charge);

II. Capacity detection mode (FAST TEST, NOR TEST) two kinds

(A) FAST TEST (rapid capacity test mode)

1.When the power is turned back into the battery charger, 8 seconds touch (mode key MODE)

Select (FAST TEST rapid capacity test mode), then press (current selection key CURREN) to

select the current system 8 seconds after the lock of your choice to work. Quick Reference

Table a capacity test procedure

 FAST TEST-- enter selected current - battery discharge - recharge --End

Is the first battery is discharged, then the battery is fully charged battery in order to detect 

and record the battery capacity.

Note that this product capacity test mode, the discharge mode is divided into two kinds, when you

select the charge current (300mA, 500mA), the system automatically default discharge current of 

250mA, when you select the charge current (700mA, 1000mA) , the system automatically default

discharge current of 500mA

(B) NOR TEST (normal capacity detection mode)

1.NOR TEST mode: is the first battery is full, then the battery discharge discharge capacity to 

detect and record the battery capacity after the battery is fully automated; capacity

detection process with reference to Table II

NOR TEST-- enter selected current charge - battery recharge and discharge --End

2. When the power is turned back into the battery charger, 8 seconds touch (mode key MODE), NOR 

TEST mode is selected, in any mode, press mode button for 2 seconds, you can enter NOR TEST mode;

3. After entering the NOR TEST mode, you can select the current key (CURREN) select 300mA, 500mA, 

700mA within 8 seconds, or 1000 mA current, the current system is locked after you select in 8 

seconds, if in this 8 the second, did not make the set, then the system will automatically lock 

500mA current charging (when selected current is the default charging current is automatically 

selected when the discharge discharge current 250mA), in which within 8 seconds, Select 700mA or 

1000mA current charge, will automatically select the discharge current of 500mA discharge.

4. When the battery is full, the system automatically to discharge, the discharge current to 

system defaults (select the charging current relationship), and record discharge data to detect 

the battery capacity, when the screen appears, capacity test mode is finished, At this parameter 

LCD display is the actual capacity of the battery reference value;.

5. capacity test mode is finished, the charger will be selected current parameters again before 

charging the battery until full.

Five, USB 5V output

5.1 USB 5V move only as output, the output current of 1000mA, connect the power USB output is 


5.2 When the battery into the slot to be exported and USB / 5V for-awake, now ready to 5V power 

supply and electronic products.

4 battery slot 5.3 product, any one slot for the USB output can be recommended are two slots in 

the battery.
