Operating Instructions

Connect to a power source: Connect the NEW i2 to an external power source (such as a car adaptor, power socket) via its charging cable. Install batteries: Put one or two batteries in each independently-controlled slot according to the polar mark on the charger.
Battery identification: Four LEDs go up over the slot a Lithium battery is inserted in; two lower LEDs go up over the slot a Ni-MH battery is inserted in. Charging begins in two seconds.
Other features: The New i2 has reverse polarity protection and anti-short circuiting protection incorporated.

Battery Activation and Inspection	Error Report
Batteries inserted with polar reversed	Four LEDs on the screen blink to

notify the user of an error.
Batteries short-circuited
The NEW i2 will charge normal batteries upon inspection.

Smart charging: The NEW i2 can choose to charge currents based on intelligent detection about battery types and capacities. The manual charging current selection is also available. The NEW i2 is compatible with:

3.7V Li-ion rechargeable batteries
3.8V Li-ion rechargeable batteries
1.2V Ni-MH/Ni-Cd rechargeable batteries

Note:

When 1A charging current is selected, the LED next to the 1A mark goes on.
For small capacity batteries (<1200mAh, such as 10440, 16340), 500mAh charging current is automatically selected.
For Ni-MH batteries and 3.7V Li-ion batteries, the NEW i2 automatically selects proper charging modes. For LiFePO4 batteries, a manual setting is required.

Charging Voltage Settings

For LiFePO4 batteries:
Insert the batteries into the NEW i2’s charging slots. After battery inspection, press the button over the battery’s slot to enter Manual Settings mode. Press and hold the V button to enter Voltage Selection. Before the button is released, three settings of charging cut-off voltages will cycle every second (highlighted with an LED). When the desired setting is highlighted, release the V button, and press the button over the slot again to exit Manual Settings mode and begin charging. For 3.8V Li-ion batteries: Follow the above setting method.
Battery Activation
The NEW i2 is capable of activating depleted Li-ion batteries with a protective circuit. After battery installation, the NEW i2 will test and activate the battery before charging. A battery detected as damaged cannot be activated, and the three LEDs above its slot will go on to notify the user.
Lithium Battery Recovery
Upon insertion of a 0V IMR battery, all four LEDs over its slot will blink to indicate that it is not ready for charging. Press and hold both buttons until its power indicator blinks to enter the Recovery mode. Nitecore recommends abandoning this battery if it fails to be recovered after several attempts. NOTE: Do not conduct battery activation operation when batteries are inserted with reversed polarity. Doing so may cause fire or explosion of the batteries.
Overtime Charging Protection
The NEW i2 will separately calculate the charging time of each battery. When the overall charging time exceeds 20 hours, the NEW i2 will automatically stop charging and display a fully charged status. This is to prevent possible overheat or even explosion due to battery quality issues.
Precautions

Safety Instruction for Lithium-ion Batteries

Charging Voltage
Lithium-ion (Li-ion) batteries have strict requirements for voltage control. Charging Li-ion batteries with electric voltage beyond safety standards can lead to battery damage and explosion.
(1) 4.2V Li-ion Batteries/ IMR Batteries 4.2V 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) 4.35V Li-ion Batteries 4.35V 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 4.35V, otherwise, the charger will charge at 4.2V by default, and cannot provide adequate charging voltage.
(3) 3.7V LiFePO4 Batteries 3.7V LiFePO4 batteries have LiFePO4 and/or 3.2V marks on the skin. Be careful with this type of battery. Without manual setting, our chargers will charge this type of battery with 4.2V voltage 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.
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 a 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 the appropriate charging current (smaller than 1C).
Precautions
(1) Do not short circuit the battery in any way. (2) Do not use a 4.2V/4.3V Lithium battery when its voltage is lower than 2.8V, otherwise, it can be over-discharged, and/or prone to an explosion at the next charging. (3) We strongly recommend batteries with protective circuits. For batteries without protective circuits (such as IMR batteries), please stay alert for over- discharge and short circuits.
(4) Do not discharge a battery with a discharging current larger than its maximum rated current.
Long-term Storage
The best storage voltage for 4.2V/4.35V rechargeable Lithium batteries is 3.7V. Voltage 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. The validation code and QR code on the package can be verified on the Nitecore web
1. The charger must be used with Nitecore’s official cords. During charging, third-party cords can cause malfunction, overheat and even fire on the charger. Damages from using unofficial cords cannot be covered by an official warranty.
2. The NEW i2 is restricted to charging Li-ion, IMR, 3.7V LiFePO4, Ni-MH/Ni- Cd rechargeable batteries only. Never use the NEW i2 with other types of batteries as this could result in battery explosion, cracking or leaking, causing property damage, and/or personal injury.
