Nitecore Superb Charger SC4 Guia Del Usuario página 3

Overtime Charging Protection
The SC4 will separately calculate the charging time of each battery. When the overall charging time exceeds ten
hours, it will automatically stop charging and display a fully charged status. This is to prevent possible overheat
or even explosion due to battery quality issue.
USB Charging
The maximum charging current for the USB output is 2.1A. During charging, the output of USB is inhibited until
the batteries are fully charged.
Precautions
1. The charger is restricted to charging Li-ion, IMR, LiFePO4, Ni-MH/Ni-Cd rechargeable batteries only. Never
use the charger with other types of batteries as this could result in battery explosion, cracking or leaking,
causing property damage and/or personal injury.
2. The safe operation temperature for the charger is between -10-40°C, and the safe storage temperature is
-20-60°C.
3. Please charge batteries in accordance with the specifications on the back. Do not charge a battery pack with
the charger.
4. Observe polarity diagrams located on the charger. Always place the battery cells with positive tip facing the
top.
5. Do not leave a working charger unattended. If any malfunction is found, please terminate operation
immediately, and turn to user manual for instruction.
6. The charger is designed for adults. Use of the charger by kids under age must be under supervision.
Operation, using or cleaning of the charger may NOT be done by kids aged 8 years or younger.
7. Please make sure the correct program and settings are chosen and set. Incorrect program or setting may
damage the charger, or cause fire or explosion.
8. Never attempt to charge primary cells such as Alkaline, Zinc-Carbon, Lithium, CR123A, CR2, or any other
unsupported chemistry due to risk of explosion and fire.
9. Do not charge a damaged IMR battery as doing so may lead to charger short-circuit or even explosion.
10. Never charge or discharge any battery having evidence of leakage, expansion/swelling, damaged outer
wrapper or case, color-change or distortion.
11. Use the original adapter and cord for power supply. To reduce the risk of damage to the power cord, always
pull by connector rather than the cord. Do not operate the charger if it appears damaged in any way.
12. DO NOT store or use the product in an environment where the temperature is extremely high / low or
changes rapidly, or in a confined area with a high temperature.
13. Please operate the charger in a well-ventilated area. Do not operate or store it in damp area. Keep all the
inflammable volatile substances away from operating area.
14. Avoid mechanical vibration or shock as these may cause damage to the device.
15. Do not use short-circuit slots or other parts of the device. Do not allow metal wires or other conductive
material into the charger.
16. Do not touch hot surfaces. The rechargeable batteries or the device may become hot at full load or high
power charging/discharging.
17. Do not overcharge or over discharge batteries. Recharge drained batteries as soon as possible.
18. Remove all batteries and unplug the charging unit from the power source when not in use.
19. Opening, disassembling, modifying, tampering with the unit may invalidate its guarantee, check warranty
terms.
20. Do not misuse in any way! Use for intended purpose and function only.

1. Charging Voltage
Lithium-ion (Li-ion) batteries have strict requirement on voltage control. Charging Li-ion batteries with electric
voltage beyond safety standard can lead to battery damage and explosion.
(1) 3.7V Li-ion Batteries/ IMR Batteries
3.7V Li-ion batteries are the most common rechargeable Lithium batteries. The skins of these batteries
are often marked with 3.6V/3.7V signs. If our chargers judge that an inserted battery is a Li-ion battery,
the battery will be automatically charged in 4.2V standard charging mode. You do not need extra voltage
settings for these types of batteries.
(2) 3.8V Li-ion Batteries
3.8V Li-ion batteries are comparatively rare. It usually has a 3.7V mark on its skin. Normally its seller will
inform its buyer that it needs to be charged with 4.35V power. When charging this type of battery, please
manually set the charging voltage to 4.3V, otherwise the charger will charge at 4.2V by default, and
cannot provide adequate charging voltage.
(3) 3.2V LiFePO4 Batteries
3.2V LiFePO4 batteries have LiFePO4 and/or 3.2V marks on the skin. Be careful with this type of
batteries. Without manual setting, our chargers will charge this type of batteries with 4.2V, and will
damage or even explode the battery with excessive charging voltage. You need to manually set the
charging voltage to 3.7V for safe charging.
2. Charging Current
For all rechargeable Lithium batteries (including Li-ion, IMR and LiFePO4 batteries), we suggest not using
current larger than 1C* for charging. For small capacity batteries, the charging current must be smaller than
1C.
*C=Capacity of a battery. For example, 1C in a 2600mAh rechargeable Lithium battery is 2.6A. 1C in a
3400mAh rechargeable Lithium battery is 3.4A.
Excessively large charging current will lead to great amount of heat, and consequently battery damage and
explosion.
Warning: Our chargers automatically judge and select charging current by the batteries' length.
For some long but small capacity batteries (i.e. 12650, 13650, 14650, 16650), please manually set
appropriate charging current (smaller than 1C).
3. Precautions
(1) Do not short circuit the battery in any way.
(2) Do not use a 3.7V/3.8V Lithium battery when its voltage is lower than 2.8V, otherwise it can be over-
discharged, and/or prone to explosion at next charging.
(3) We strongly recommend batteries with protective circuit. For batteries without protective circuit (such as
IMR batteries), please stay alert for over-discharge and short circuit.
(4) Do not discharge a battery with a discharging current larger than its maximum rated current.
4. Long-term Storage
The best storage voltage for 3.7V/3.8V rechargeable Lithium batteries is 3.7V. The voltage is too low or too
high can damage your battery during storage. You can discharge a battery to 3.7V, or charge it to 3.7V in a
charger before you keep it in long-term storage.
