NEW i4 User Manual

Operating Instructions

Power on: Connect the NEW i4 to an external power source (such as vehicle adaptor, power socket) with its charging cor d.

Battery placement: Put one battery in each independently controlled slot according to the polar mark on the charger.

Battery identification: All Four LEDs indicators will be lit when Lithium batteries are placed in, two lower LEDs will be lit when Ni-MH batteries are placed in. Charging begins in two seconds.

Other features: The New i4 has reverse polarity protection and anti-short circuiting protection incorporated.

Smart charging: The NEW i4 adopts the appropriate charging currents based on battery types and capacities. Whilst the option to adjust the current is also available. The NEW 14 is compatible with:

• 7V Li-ion rechargeable batteries
• 8V Li-ion rechargeable batteries
• 2V Ni-MH/Ni-Cd rechargeable batteries
• 2V LiFePO4 batteries

Default Charging Parameters

In the context of this user manual, batteries of more than 1200mAh and equal or longer than 65mm in length will be defined as large capacity, batteries of less than 1200mAh and shorter than 65mm in length will be defined as small capacity. The default charging current allocation for the NEW i4 is shown in the table below:

Types and capacities| Default power allocation to each slot| Manual adjustment to current
---|---|---
1 battery| 2 batteries| 3 batteries| 4 batteries
Lithium
batteries| Large capacities| 1.5A| 0.7SA| 0.75A/0.75A Average current1| 0.375A| Yes
Small capacities| 0.5A| 0.5A| 0.5A/0.75A Average current2| 0.375A| No
NI-MH| O.SA| O.SA| 0.5A/0.75A Average current*2| 0.375A| No

*1 When charging three batteries of large capacities, the battery in the second slot will be charged at 0.75A, whilst the other two batteries will be charged at 0.375A each.

*2 When charging three batteries of small capacities, the battery in the second slot will be charged at O.SA, whilst the other two batteries will be charged at 0.375A each.

Settings

After battery placement, press the C button to select a slot or press the button repeatedly to select a specific slot from left to right order, when the desired slot is selected, holding down the C button allows for manual adjustment to charging current and holding down the V button allows for manual adjustment to voltage.

‘Current setting

This option allows the charging current to be set at 1.5A for batteries of large capacities. The red light on top will turn on when the charging current to set at 1.5A.

‘Voltage setting

This option allows the charging termination voltage to be set at 4.35V/4.2V/3.7V
Note: (2) Charging current allocation can be manually adjusted when more than one battery of large capacities are placed in the charger

Trickle Charge Mode

The New i4 will charge batteries of small capacities at 0.5A.

Active Current Distribution (ACD)

The ACD technology allows the NEW i4 to actively distribute all its power between all slots in an orderly manner, for instance:

When one or more batteries are set to be charged at an accelerated rate of 1.5A

1. The charger will charge the batteries that are set to be charged at 1.5A from left to right
2. When the first battery charging at 1.5A is almost fully charged and enters CV charging, the charger will divert a portion of its current to charge other batteries that are to be charged at the default setting, then proceed to charge the second battery that are set to be charged atSA when the first one gets fully charged.
3. When all batteries that are set to charge at 1.5A are fully charged, the charger will begin to charge the other remaining batteries at its default

Note: When only one battery of large capacity is placed in the charger, the charger will charge it at 1.SA by default.

Battery Recovery Mode

The NEW i4 has a revival function designed specifically to revive over- discharged IMR batteries, an over-discharged IMR battery is indicated by the four flashing LED indicators above the particular slot the battery is placed in, holding down both C and V buttons until the bottom indicator starts flashing to enable the battery recovery process. IMR batteries that have been severely over-discharged may not be recovered successfully.

Caution: Do NOT enter battery recovery mode when the battery is inserted backward, it may cause fire and explosion.

Overcharging Timeout Protection

The NEW i4 monitors each slot individually and keeps records of the charging duration for each battery. The charger automatically terminates the charging process for any particular battery that has been in the charging process for 20 hours but is not fully charged, and the charging indicators will show full power status. This is designed to eliminate overcharge, overheating, and explosion concerns arising from battery duality issues.

Precautions

Safety Instruction for Lithium-ion Batteries

1. 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 U-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 U-ion Batteries

4.3W 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 4.3W, otherwise, the charger will charge at 4.2V by default, and cannot provide adequate charging voltage.

(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.

2. Charging Current

For all rechargeable Lithium batteries (including Li-ion, IMR, and UFePO4 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).

3. Precautions

• Do not short circuit the battery in any way.
• 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.
• We strongly recommend batteries with protective For batteries without protective circuits (such as IMR batteries), please stay alert for over-discharge and short circuits.
• Do not discharge a battery with a discharging current

4. 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.
