Nitecore New i4 Intellicharger Battery Charger

Nitecore I4 IntelliCharger is a smart four-bay battery charger for rechargeable Li-ion, IMR, NiMH and Ni-Cd cells. It charges up to four batteries at once, detects battery type, selects suitable current, and supports multiple voltages for flexible everyday use.

This Nitecore New i4 Intellicharger chargers uits users who need one reliable charger for vape batteries, torches, camera accessories, electronic tools, radios, and household rechargeable cells.

Why Choose the Nitecore New i4 Intellicharger?

Nitecore New i4 Intellicharger improves charging speed, battery compatibility, and safety control compared with the older i4 model. It supports independent charging slots, automatic current selection, 0V IMR recovery, and non-rechargeable lithium battery detection.

Here are key benefits of Nitecore New i4 Intellicharger:

• Charges up to four batteries independently.
• Delivers up to 1500mA current in one slot.
• Supports 1.2V, 3.7V, 4.2V and 4.35V batteries.
• Selects current automatically based on battery capacity.
• Redirects power with Active Current Distribution Technology.
• Protects cells with overcharge, reverse polarity and short-circuit safeguards.
• Includes a 3 pin UK plug for UK mains sockets.

What Makes the Nitecore I4 IntelliCharger Faster?

Nitecore I4 IntelliCharger uses 100% Charging Acceleration to charge faster than the original i4. One battery can receive up to 1500mA, while two batteries can receive up to 750mA per bay, depending on slot use and battery condition.

Charging setup	Maximum charging output
1 battery inserted	Up to 1500mA
2 batteries inserted	Up to 750mA per bay
Multiple batteries inserted	Current adjusts automatically
4 batteries inserted	Up to 375mA per bay

This smart distribution helps reduce charging time without forcing unsuitable current into smaller cells.

How Does Active Current Distribution Technology Work?

Active Current Distribution Technology sends available charging power to the battery that needs it most. When one battery finishes charging, the charger can move more charging power to the remaining active bay.

This feature matters because battery slots rarely finish at the same time. Different capacities, chemistries and discharge levels need different charge durations. The I4 manages that process automatically.

Which Batteries Does the Nitecore Intellicharger I4 Support?

Nitecore Intellicharger I4 battery charger supports a wide range of rechargeable cylindrical batteries, including common vape, torch and household cell formats.

Battery category	Supported examples
Li-ion / IMR / LiFePO4	10340, 10440, 14500, 16340, 17335, 17500, 17670, 18490, 18650, 20700, 21700, 22650, 25500, 26650
NiMH / Ni-Cd	AA, AAA, AAAA, C, D
Voltage support	1.2V, 3.7V, 4.2V, 4.35V

The NITECORE I4 INTELLICHARGER 18650 26650 compatibility makes this charger useful for high-drain cells used in LED torches, vaping devices and outdoor equipment.

Can Each Slot Charge Independently?

Yes. Each bay on the Nitecore New i4 Intellicharger Four Bay Li-ion/NiMH Charger works independently. You can charge different battery sizes, chemistries and capacities at the same time when the batteries are compatible with the charger.

The C button selects a charging slot. The V button changes compatible voltage settings where manual selection is required. This design gives better control than a basic charger with fixed output.

What Safety Features Does the Nitecore I4 IntelliCharger Include?

Nitecore I4 IntelliCharger includes safety systems that support controlled battery charging. These features reduce risk when the charger is used correctly with rechargeable batteries.

Safety feature	What it does
Reverse polarity protection	Detects incorrectly inserted batteries
Short-circuit prevention	Helps prevent unsafe current flow
Non-rechargeable lithium detection	Alerts you with flashing LED indicators
Overtime charging protection	Limits charging time to around 20 hours
Flame-resistant materials	Supports safer charger construction
Heat dissipation design	Helps control operating temperature
IMR charging optimisation	Keeps end voltage within safe limits

Always use the Nitecore i4 Intellicharger manual before charging unfamiliar batteries.

How Does IMR Battery Restoration Work?

Nitecore I4 IntelliCharger includes IMR Battery Restoration for certain depleted IMR cells. This mode can attempt to recover a compatible 0V IMR battery by using the charger’s restoration function.

To activate the restoration mode, insert the battery correctly, then press and hold the C and V buttons together. Battery recovery is not guaranteed. Damaged, swollen, leaking or non-rechargeable cells must not be charged.

How Do the LED Indicators Work?

The LED indicators show battery status during charging. While a battery charges, the green LEDs show progress. When charging finishes, the LEDs become steady green.

The charger can also use flashing LEDs to warn about unsupported or unsafe cells, including non-rechargeable lithium batteries.
