Characteristics:
1. Four charging current adjustments (300mA/500mA/700mA/1000mA);
2. It is possible to charge batteries of different specifications (18650/26650.../AA/AAA) simultaneously;
3. This charger adopts an independent LCD display with voltage (V) Current (mA) Time (h) Capacity (mAh) internal resistance (mR) parameter, E is clear;
4. In CHARGE mode, 4 channels work independently, and different charging currents can be selected for charging and mixed charging of lithium-ion batteries and nickel hydrogen batteries.
In FAST TEST mode, 4-channel can quickly detect battery capacity, regardless of lithium-ion or nickel hydrogen batteries, both of which operate independently. The process of quickly detecting battery capacity consists of two steps (1 discharge, 2 full charge)
6. NOR TEST mode, the normal process of detecting battery capacity consists of three steps (1) fully charging, 2) discharging, and 3), and the process of detecting battery capacity;
7. CHARGE and FAST TEST/ The three modes of NOR TEST can work simultaneously; Independently set charging/fast capacity detection/normal capacity detection functions;
8. Multiple protection functions: overcharging and discharging, short circuit, temperature, 0V voltage activation function- Δ V&0 Δ V) 1.65V-2.2V cannot be charged, intelligent identification of faulty batteries and reverse battery detection protection.
9. With standard 5V/1000 mA USB output function: USB output is completed from 1 lithium battery to 4 lithium batteries. This product's nickel hydrogen battery cannot have USB output.
10. Equipped with a dedicated power adapter: DC input voltage: 12V/2A.

 Description of buttons:
1. The charger has 6 buttons, including mode selection button (MODE), current selection button (CURREN), and independent selection and viewing data button (1234), making it simple and convenient to use;
2. In any case, press and hold the MODE key for 3 seconds to change the CHARGE mode or FAST TEST, NOR TEST mode. Then, within 8 seconds, lightly press the corresponding button of the function again to change it. After selecting the current, independent, mixed charging, capacity detection, and other functions, it will enter the working state for 8 seconds. In the working state, lightly press the (1234) key, View the reference values of current (mA)/capacity (mAh)/voltage (V)/time (h)/internal resistance (mR) data.
4、 Mode operation instructions:

CHARGE (charging mode):
When the charger is powered on, all LCD screens of the charger will instantly light up. If the battery is not inserted, it will display null, and if the battery is damaged, it will also display null;
2. Insert the charger into the battery and connect it to the power supply. The charger measures the internal resistance of the battery in about 3 seconds, and then the system automatically enters charging mode (CHARGE), The charger automatically defaults to a charging current of "500mA" and can be selected through the current selection button (CURREN) within 8 seconds Select a current of 300mA, 500mA, 700mA, or 1000mA for charging. After 8 seconds, the system will lock the current you have selected for charging. If no setting is made within 8 seconds, the system will automatically default to charging at 500mA. At this time, the current and other functions cannot be changed. If you need to change it, press and hold the mode key to select from;
3. In charging mode (CHARGE), within 8 seconds, you can change the independent charging or different current selection, as well as mix charging of different batteries. Easy to operate, lightly press the corresponding button of the 1234 battery within 8 seconds, then press the mode key to change the mode, press the current key to change the current, independent, mixed charging, and capacity detection functions. After 8 seconds of selection, it enters the working state. Pay attention to selecting the charging current based on the battery capacity size. If fast charging is not necessary, it is recommended to use 500mA charging, which is the safest;
4. In charging mode, by lightly pressing the 1234 key, you can switch and view the charging capacity (mAh), charging time (h), battery internal resistance (mR), charging current (mA), and voltage (V) in 5 units. After the battery is fully charged, it will be displayed (charging end);
2、 Two capacity detection modes (FAST TEST and NOR TEST)

 FAST TEST (Fast Capacity Detection Mode):
1. After the charger is inserted into the battery and connected to the power supply, press the (mode key MODE) lightly within 8 seconds to select (FAST TEST fast capacity detection mode), and then press the (current selection key CURREN) to select the desired current. After 8 seconds, the system will lock the one you have selected for operation. Refer to Table 1 for the rapid capacity testing process
It is to first discharge the battery, then fully charge the battery and record the charging level to test the battery capacity.
When using the capacity detection mode for this product, there are two discharge modes. When you choose a charging current of (300mA, 500mA), the system automatically defaults to a discharge current of 250mA. When you choose a charging current of (700mA, 1000mA), the system automatically defaults to a discharge current of 500mA,

NOR TEST (normal capacity detection mode):
1. NOR TEST mode: It is to first fully charge the battery, then discharge the battery and record the discharge amount to detect battery capacity, and then automatically charge the battery; Refer to Table 2 for the capacity testing process
2. After the charger is inserted into the battery and connected to the power supply, lightly press the (mode key MODE) within 8 seconds to select the NOR TEST mode. Press and hold the mode key for 2 seconds in any state to enter the NOR TEST mode;
3. After entering NOR TEST mode, within 8 seconds, you can use the current selection key (CURREN) to select 300mA, 500mA, 700mA, or 1000mA current. After 8 seconds, the system will lock the current you have selected. If no setting is made within these 8 seconds, the system will automatically lock the 500mA current for charging (the selected current is the default charging current of the system, and the discharge current will be automatically selected as 250mA during discharge). Within these 8 seconds, Select 700mA or 1000mA current for charging, and the discharge current will automatically be selected as 500mA during discharge.
4. When the battery is fully charged, the system automatically switches to discharge. The discharge current is set to the system default value (the current when charging is selected is related), and the discharge data is recorded to detect the battery capacity. When the screen appears, the capacity detection mode ends, and the parameters displayed on the LCD screen are the actual capacity reference value of the battery;.
After the capacity detection mode ends, the charger will charge the battery again with the previously selected current parameters until it is fully charged.

USB 5V output:
5.1 USB is only used as a 5V mobile output, with an output current of 1000mA. Connecting to the power supply for USB output is invalid.
5.2 When the battery is placed in the slot and about to output USB/5V for replacement, the 5V electronic product can be powered at this time.
There are four battery slots in the 5.3 product, and any slot can be USB output. It is recommended to place batteries in both slots.
5.4 USB 5V output is only valid for 3.7V lithium batteries, and nickel hydrogen boost is invalid.
