The Nitecore i2 Battery Charger is an intelligent dual-slot charger designed for compatible rechargeable Li-ion, IMR, Ni-MH, and Ni-Cd batteries. Its two independently controlled charging bays allow different supported batteries to be monitored and charged at the same time, while three-color LED indicators make it easy to follow charging progress.

For customers searching for a Nitecore i2 Battery Charger Dubai, Nitecore i2 2 Bay Charger, Nitecore i2 18650 Charger, or Nitecore i2 Intellicharger, the original i2 provides a straightforward charging solution with automatic battery detection, 500mA × 2 output, multiple charging modes, and built-in protection features.

The original i2 should not be confused with the newer NITECORE NEW i2, which has different charging speeds and a wider battery compatibility range.

What Is the Nitecore i2 Battery Charger?

The Nitecore i2 Battery Charger is a two-slot intelligent charger developed for several common rechargeable battery formats.

Each charging slot operates independently. This means the charger can monitor the battery placed in each bay separately and apply the appropriate charging process for supported battery chemistry.

The original i2 supports rechargeable Li-ion and IMR cells, as well as compatible Ni-MH and Ni-Cd batteries. NITECORE’s original manual specifies an output of 500mA × 2 and two independent charging channels.

The Nitecore i2 Battery Charger is an intelligent dual-slot charger featuring 500mA × 2 charging, independent charging channels, 3-color LED indicators, automatic battery detection, and support for compatible Li-ion, IMR, Ni-MH, and Ni-Cd rechargeable batteries.

Two Independent Charging Slots

The Nitecore i2 2 Bay Charger contains two charging channels that work independently.

This gives users flexibility when charging compatible rechargeable batteries. The two cells do not necessarily need to be identical in capacity or size, provided both are supported by the charger.

For example, a compatible 18650 lithium-ion cell can be placed in one channel while another supported rechargeable battery is placed in the second.

The charger monitors each bay individually rather than treating both batteries as a single pair.

500mA × 2 Charging Output

The original Nitecore i2 has an official charging output of:

500mA × 2

This means each charging channel can provide up to approximately 500mA under its standard operating configuration.

This specification is important because some online listings mix information from the original i2 with the newer NEW i2.

The original i2 should not be described as a 1000mA-per-slot charger.

The upgraded NEW i2 can provide 500mA × 2 or 1000mA × 1, which is one of the major differences between the two generations.

Nitecore i2 Compatible Batteries

The original Nitecore i2 Intellicharger supports a useful range of rechargeable battery sizes.

According to NITECORE’s original manual, supported Li-ion and IMR formats include:

26650, 22650, 18650, 17670, 18490, 17500, 18350, 16340/RCR123, 14500 and 10440.

For Ni-MH and Ni-Cd rechargeable batteries, the original i2 supports:

AA, AAA, AAAA and C.

Always confirm both battery chemistry and voltage before charging. A battery physically fitting into a slot does not automatically make it electrically compatible.

Nitecore i2 for 18650 Batteries

The Nitecore i2 18650 Charger supports compatible rechargeable 18650 Li-ion and IMR batteries.

Because the two slots are independent, users can charge one or two compatible 18650 cells simultaneously.

Before inserting an 18650 battery, inspect its exterior carefully. Do not charge a cell showing severe wrap damage, leakage, swelling, corrosion, dents, abnormal heat, or other signs of physical failure.

Does Nitecore i2 Charge 26650 Batteries?

Yes. The original i2 compatibility list includes 26650 rechargeable Li-ion/IMR batteries.

The charger’s adjustable contact design accommodates several cylindrical cell sizes, including 26650 and 18650 formats.

Does Nitecore i2 Charge AA Batteries?

Yes, provided they are compatible rechargeable Ni-MH or Ni-Cd AA batteries.

Do not use the charger with ordinary disposable alkaline AA batteries.

The same rule applies to rechargeable AAA, AAAA, and C cells supported by the original i2.

3-Color LED Charging Indicators

Unlike the Nitecore D2 and D4 models, the original i2 does not use an LCD display.

Instead, it uses three-color LED indicators to communicate battery charging progress and status. NITECORE’s original documentation identifies the LED system as part of the charger’s charging-status interface.

This distinction is useful when comparing the i2 with other Nitecore chargers.

If you specifically want an LCD-based charger, models such as the D2 or D4 belong to a different Nitecore product family.

Automatic Battery Detection

The Nitecore i2 is designed to detect the status of compatible batteries and apply an appropriate charging process.

For supported rechargeable cells, the charger manages charging without requiring the user to manually set current for each normal charging cycle.

This makes the i2 particularly straightforward for customers who want a dual-slot charger without a complex control interface.

CC, CV and Trickle Charging

The original Nitecore i2 uses different charging methods according to compatible battery chemistry and charging stage.

Its documented modes include CC, CV, and trickle charging.

Constant-current and constant-voltage charging are associated with compatible lithium-based cells, while the charger can use an appropriate charging approach for supported Ni-MH and Ni-Cd rechargeable batteries.

Users do not need to manually calculate the charging stage during normal operation.

How to Use the Nitecore i2 Charger

Connect the charger to a compatible power source, then insert the rechargeable battery with the positive and negative ends aligned with the polarity markings inside the charging bay.

Check the LED indicators to confirm that the charger has recognized the cell and started the charging process.

If using two batteries, each bay will monitor its battery independently.

Allow the charger to complete the charging cycle and remove the batteries when charging is finished.

The manufacturer advises users to observe correct polarity and not leave a working charger unattended.

How Long Does the Nitecore i2 Take to Charge?

There is no single charging time that applies to every battery.

Charging time depends primarily on:

• Battery capacity
• Remaining charge
• Battery chemistry
• Cell age and condition
• Effective charging current

Because the original i2 provides up to approximately 500mA per slot, a high-capacity battery generally takes longer than it would on a newer charger designed for higher charging currents.

For example, you should not compare the original i2 directly with the NEW i2’s maximum 1000mA single-slot charging mode.

Automatic Charging Termination

The Nitecore i2 Smart Charger is designed to stop the normal charging process automatically when a supported battery reaches the appropriate full-charge condition.

This helps prevent continuous uncontrolled charging after completion.

Automatic charging management does not replace normal battery-safety practices. Batteries should still be inspected before charging and removed appropriately once charging is complete.

Reverse Polarity Protection

The original Nitecore i2 includes reverse-polarity protection.

If a battery is inserted in the wrong direction, the charger is designed to prevent normal charging from proceeding.

However, users should always follow the polarity symbols inside the charger rather than relying on the protection system.

Heat Dissipation and Charger Placement

The i2 is designed with heat management in mind, but all rechargeable battery chargers should be operated in a suitable environment.

NITECORE specifies a safe operating-temperature range of 0°C to 40°C for the original i2 and advises against use or storage near flames, direct sunlight, heating equipment, or other high-temperature environments.

Use the charger on a stable, dry surface with adequate ventilation.

Original Nitecore i2 vs NEW i2

This is one of the most important distinctions to understand before buying.

Feature	Original Nitecore i2	Nitecore NEW i2

4.35V Battery Support	Not listed	Yes

The NEW i2 is officially described by NITECORE as an upgraded version of the i2 with increased charging speed, broader compatibility, and Active Current Distribution technology.

This is why specifications from the two products should not be mixed on the same product listing.

Does Original Nitecore i2 Support 21700 Batteries?

The original i2 manual does not list 21700 among its compatible battery sizes.

The newer NEW i2, however, officially lists selected flat-top 21700 batteries among its compatible formats.

Therefore, if the product being sold is the original i2, it should not be marketed as a 21700 charger.

Does Original Nitecore i2 Support 20700?

The same distinction applies to 20700 batteries.

20700 is not listed in the original i2 compatibility information, while the NEW i2 officially supports selected flat-top 20700 cells.

Does Original Nitecore i2 Support LiFePO4?

LiFePO4 charging is not listed in NITECORE’s original i2 specification.

The upgraded NEW i2 does officially include LiFePO4 support.

For an original i2 product page, avoid adding LiFePO4 simply because it appears on NEW i2 listings.

Nitecore i2 vs Nitecore D2

Both models provide two independently controlled charging slots, but they differ in their user interface and supported charging functions.

Feature	Nitecore i2	Nitecore D2
Charging Slots	2	2
Independent Channels	Yes	Yes
Main Interface	LED Indicators	Digital LCD
18650 Support	Yes	Yes
Ni-MH / Ni-Cd	Yes	Yes
Detailed On-Screen Information	No	Yes
General Design	Simple intelligent charger	Digital intelligent charger

The i2 is better suited to buyers who want straightforward LED-based charging, while the D2 provides more detailed visual charging information through its digital display.

Nitecore i2 vs Basic 2-Bay Charger

A basic dual-slot charger may simply supply current and use a basic indicator for charging status.

The Nitecore i2 Intelligent Charger adds independent charging channels, automatic battery detection, multiple supported chemistries, automatic charging termination, and protection features.

This broader feature set is why search terms such as Nitecore i2 Intellicharger, Nitecore i2 Smart Charger, and Nitecore Dual Slot Battery Charger are relevant to this product.

Why Is My Nitecore i2 Not Charging a Battery?

If a battery is not being recognized, first check the polarity and make sure both battery contacts are making proper contact with the charger.

Then check the battery condition.

A damaged, excessively discharged, incorrectly sized, or unsupported battery may fail to charge normally.

Also confirm that the battery chemistry is supported by the original i2.

If the battery is a 21700, 20700, LiFePO4, or another format only listed for newer chargers, do not assume it will work simply because it can physically fit.

What Batteries Should Not Be Used?

Do not charge unsupported or non-rechargeable batteries in the original i2.

The original manufacturer manual restricts the charger to supported Li-ion, IMR, Ni-MH, and Ni-Cd rechargeable batteries and warns against using other battery types.

Disposable alkaline batteries should never be placed into the charger for recharging.
