Safety Instruction for Lithium-ion Batteries

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.

Validation code and QR code on package can be veried on Nitecore website.

1.The charger must be used with Nitecore’s ocial cords. During charging, third party cords

can cause malfunction, overheat and even re on the charger. Damages from using unocial

cords cannot be covered by ocial warranty.

2.The SC4 is restricted to charging Li-ion, IMR, 3.2V LiFePO4, Ni-MH/Ni-Cd rechargeable

batteries only. Never use the SC4 with other types of batteries as this could result in battery

explosion, cracking or leaking, causing property damage and/or personal injury.
