Nitecore i2 Battery Charger

This product is unavailable

The Nitecore i2 is able to automatically identify Li-ion, LiFePO4, Ni-MH and Ni-Cd rechargeable batteries and apply the appropriate charging mode: Constant Current (CC), Constant Voltage (CV), or Trickle Charge.

Each battery bay has its own micro processor that is capable of monitoring and charging batteries independently.

Looking to charge more than two batteries at once? Check out the NiteCore Intellicharger D4 or the Efest LUC Blu6 Charger (Blue Tooth).

What's New In The Updated Intellicharger i2?

  • LCD screen replaces old i2 power bar
  • 100% charging acceleration
  • Active current distribution technology
  • Expanded compatibility to support 3.7V and 4.35V batteries
  • IMR battery restoration
  • Automatic current selection based on battery capacity
  • Automatic detection of non-rechargeable lithium batteries

Insert, Detect, and Charge

The most noticeable difference between the original NiteCore i2 and the upgraded version is the front face. The old yellow power bars have been replaced with a modern LCD screen and charging progress is now displayed in percentage along with green LED lights.

As with the original i2, all you have to do is insert the 18650 battery into the slot and the new i2 will automatically detect and charge.

Compact and Compatible

The New Nitecore Intellicharger i2 is a compact device that can charge batteries that are 30mm to 69.3mm long, including flat top types. Super long batteries like some protected 26650 cells might not fit into the i2 bay.

The Nitecore Intellicharger i2 is compatible with IMR, Li-ion, LiFePO4, Ni-MH, and Ni-Cd batteries. It is capable of charging two batteries simultaneously.

Li-ion/IMR/LiFePO4: 10340, 10350, 10440, 10500, 12340, 12500, 12650, 13450, 13500, 13650, 14350, 14430, 14500, 14650, 16500, 16340 (RCR123), 16650, 17350, 17500, 17650, 17670, 18350, 18490, 18500, 18650, 18700, 20700, 21700, 22500, 22650, 25500, 26500, 26650 size batteries.

Ni-MH/Ni-Cd: AA, AAA, AAAA, C, D

100% Charging Acceleration

The maximum charge current of the new i2 is now 1000mA per slot – which is double the capacity of the original i2 charger.

Active Current Distribution Technology

Active current distribution (ACD) technology enables dynamic distribution of charging power in the new i2. Let's say you are charging two batteries of different sizes. The smaller one will obviously charge faster. ACD technology automatically transfers all charging power to the bigger battery once the smaller cell is full.

Expanded Compatibility

The new Nitecore Intellicharger i2 is now compatible with 1.2V, 3.7V, 4.2V and 4.35V batteries. Press the "V" button to set the charging voltage for each slot.

IMR Battery Restoration

Press and hold the "C" and "V" buttons simultaneously to restore a depleted IMR battery.

Precise Charging Current Based on Battery Capacity

The new i2 automatically detects battery capacity and applies the appropriate charging current. For large capacity batteries like 18650 and 26650 types, press and hold the "C" button to quickly activate 1000mA fast charging.

Automatic detection of Non-Rechargeable Batteries

The new Intellicharger i2 will instantly detect a battery that is non-rechargeable and warn you through four flashing LED lights.

Intelligent Charge Mode Selection

Different batteries have different specs, which means their charging current and voltage requirements are different too. This is why you need an intelligent charger such as the Nitecore i2.

The Intellicharger is built with an integrated microprocessor that automatically identifies the type of battery inserted into the bay and selects the appropriate charging voltage and current. Once it detects battery type and battery status, the i2 will automatically apply CC, CV or -dV/dt charge mode.

Optimized for Ni-MH and Ni-Cd Batteries

The Nitecore i2 is optimized for Ni-MH and Ni-Cd batteries which are often used to power toys, digital cameras, portable music players, and other high-drain electronic devices that consume power quickly.

The -dV/dt charging program for Ni-MH and Ni-Cd batteries automatically detects battery status and determines the appropriate charging and termination voltage. This feature offers maximum power without the risk of overcharging.

Optimized for IMR Batteries

The Intellicharger is also popular among vapers who rely on IMR batteries for their mods and APVs.

With extremely low internal resistance, IMR batteries are susceptible to overcharging which could lead to safety issues when charged using regular Li-ion battery chargers. To address this problem, the Nitecore i2 incorporates an optimized IMR charging system that is able to monitor the entire charging process, ensuring that the end voltage is always within safe limits and ultimately helps extend battery life.

Overcharge Protection

The new Nitecore i2 monitors the charging time of each battery. When the overall charging time exceeds 20 hours, the i2 will automatically stop charging and display a full charge status. This prevents possible overheat or explosion due to battery defect.

Quality Materials for Maximum Safety

The Nitecore Intellicharger i2 is engineered to provide a safe and seamless user experience. The exterior shell is made of fire-retardant ABS material and all components are manufactured to the highest standards of safety.

Although the i2 can get warm when charging as most devices do, it never gets hot. The chassis is designed with multiple vents for optimal heat dissipation. The new i2 also monitors and controls internal temperature in real time to prevent overheating and ensure a stable charging process.

Down To The Finest Detail

The spring-loaded battery contact plates of the i2 are made of pure copper. This minimizes polarity electric resistance, ensures a more precise charging voltage, generates less heat, and provides a smooth sliding action when installing and removing batteries.

Indoor and Outdoor Use

The new i2 has two power connectors – one for mains input (100-240VAC 50/60Hz) and another for 12V DC input – so you can charge your batteries whether you are at home or on the road. The Intellicharger is perfectly compatible with car and wall adapters.

Error Warning

When all the LED lights flash simultaneously, it means that there is a problem with the battery. Usually this indicates reverse polarity which the Intellicharger automatically detects to prevent damage. If a battery is inserted incorrectly, the LED lights will flash quickly and "Err" will be displayed on the screen.
