Operating Instructions
Connect to power source: connect the SC4 to an external power source (wall outlet, car adapter. etc.) via its
power cord. The boot animation will be displayed on the LCD screen.
Insert batteries: The SC4 features four independently controlled charging slots. Insert batteries of supported
types into each slot according to the polarity marks on the slot. After battery installation, the SC4 begins
charging and presents Battery Status by “Good” or “Poor”, Internal Resistance, Charging Current, Battery
Voltage, Charged Volume and Charging Time on the LCD screen.
Battery inspection and error report: The SC4 has reverse polarity protection and anti-short circuiting
function.
If there are batteries inserted with polarity reversed or short-circuited, the LCD screen of relevant channel will
indicate “EE EE” and the power level display will blink to notify the user of an error.
Smart charging: The SC4 can choose appropriate charging currents based on intelligent detection about
battery types and capacities. Manual charging current selection is also available. The SC4 is compatible with:
1) 3.7V Li-ion rechargeable batteries
2) 3.8V Li-ion rechargeable batteries (4.35V±1% after fully charged)
3) 1.2V Ni-MH/Ni-Cd rechargeable batteries
4) 3.2V LiFePO4 batteries
Default Settings
The default settings (not manually congured) for the SC4 are:
• For Li-ion batteries with large capacity (>1200mAh), the default current is 2000mA, 4.2V±1%.
• For Li-ion batteries with small capacity (<1200mAh), the default current is 500mA, 4.2V±1%.
• For Ni-MH/Ni-Cd batteries, the default current is 500mA, 1.48V±1%.
Note: The SC4 can automatically select charging modes for Ni-MH batteries and 3.7V Li-ion batteries. However,
LiFePO4 batteries and 3.8V Li-ion batteries require manual settings on charging cut-o voltages.
For the battery which length is >60mm (2.4’’), the SC4 automatically identies its capacity as >1200mAh.
Key Switches
During charging, press the C switch to cycle through the charging states of 4 channels; Press the V switch to
display Battery Status, Internal Resistance, Charging Current, Battery Voltage, Charged Volume and Charging
time on the LCD screen;
Holding the C switch will enter the Manual Settings Mode; whilst holding the V switch will prioritize CH1 and
CH2 for charging.
After entering the Manual Settings Mode, press the C switch to alternate CHG. MODE, CHANNEL STATUS and
the Settings Mode of the next channel;
Press the V switch to select Charging Voltage in CHG. MODE and Charging Current in CHANNEL STATUS;
Hold the V switch to increase Charging Current in CHANNEL STATUS; Hold the C switch to exit the Manual
Settings Mode.
Charging Voltage Settings
Step 1: During charging, press the C switch to select channel and hold down the C switch to enter the settings
of selected channel;
Step 2: After entering Settings Mode, press the C switch again till the CHG. MODE is showed on the screen,
press V to select voltage (3.7V/4.2V/4.3V). After successful setup, holding down the C switch to begin
charging.
Charging Current Settings
Battery Type and Capacity Default current Max. charging current
Li-ion
batteries
>1200 mAh 2000mA 3000mA
<1200 mAh 500mA 2000mA
Ni-MH
batteries
AA/AAA 500mA 2000mA
Others 500mA 2000mA
Step 1: The same as above.
Step 2: After entering the Setting Mode, press the C switch until CHANNEL STATUS is shown on the screen;
press or hold the V switch to set the Charging Current from 300mA to 3000mA:
• For large capacity batteries (>1200mAh), the selectable Charging Current ranges from 300mA to 3000mA
(steadily increased by 100mA);
• For small capacity batteries (<1200mAh), the selectable Charging Current ranges from 300mA to 2000mA
(steadily increased by 100mA)
After the appropriate Charging Current is selected, release the C switch and hold the C switch again to exit
Manual Settings Mode and begin charging. “FULL” will appear in the CHANNEL STATUS on screen when
charging is fully complete.
Note:
1. If no further operation is done in 30 seconds in Manual Settings Mode, the SC4 will automatically begin
charging with the selected setting;
2. For large capacity batteries, 300mA-3000mA charging current is selectable; For small capacity batteries,
Nitecore suggests to select charging current below 1000mA (depends on the batteries capacity);For Ni-MH/
Ni-Cd batteries (regardless of capacity), 300mA-2000mA is suitable.
3. Do not charge Ni-MH/NiCd batteries at larger than 0.5C current. Doing so can cause overheat of the
batteries.
Charging in Priority Function
The CH1 and CH2 can be selected to charge in priority by pressing the C switch to access CH1 or CH2, then
hold the V switch to prioritize the chosen channel (CH1 and CH2 can be selected at the same time). If CH1 or
CH2 is selected to charge in priority, the other channels automatically begin charging after the battery in CH1 or
CH2 is fully charged.
Automatically Battery Internal Resistance Detection
With the SC4 switch on and batteries installed, the SC4 automatically detects and displays the Internal
Resistance in the CHANNEL STATUS. When the Internal Resistance is below 250mΩ, the LCD screen will indicate
GOOD; when it is above 250mΩ, the LCD screen will present POOR to indicate Battery Status and suggest
to replace the battery (For battery which voltage is higher than 4V, the SC4 will display the default internal
resistance 120mΩ only)
Power Detection
During charging, SC4 will automatically calculate and display Charged Volume in the CHANNEL STATUS.
Anti-short Circuiting and Reverse Polarity Protection
If there are batteries inserted with polar reversed or short-circuited, the LCD screen of relevant channel will
indicate “EE EE” and the power level display will blink.
Energy Saving Function
If there is no operation in 3 minutes, the screen will automatically dim to save energy; if there is any operation,
the screen will light again.
PID (Proportion Integration Dierentiation) System
The PID system will automatically control the charging temperature within the safety limit when charging in a
large current.
Battery Activation
The SC4 is capable of activating depleted Li-ion batteries with protective circuit. After battery installation, SC4
will test and activate the battery before charging. When a battery is detected as damaged, the power level over
the channel will blink to urge an immediate termination of charging.
Li-ion Battery Recovery
Upon insertion of a 0V IMR battery, LCD on the SC4 will blink to indicate non-rechargeable. In this situation,
press the C and V switch simultaneously to enter recovery mode, the power level display will gradually increase.
Nitecore recommends abandoning this battery if it fails to be recovered after several attempts.
NOTE: When attempting to activate an IMR battery, reverse polarity protection is temporarily disabled. Take
special care to ensure batteries are correctly inserted. Failing to do so may result in re and explosion.
