The Nitecore D2 Battery Charger is a 2-slot intelligent charger with 500mA × 2 charging, a digital LCD display, independent charging channels, and support for compatible Li-ion, IMR, LiFePO4, Ni-MH, and Ni-Cd rechargeable batteries.

Two Independent Charging Slots

The Nitecore D2 2 Bay Charger features two independently controlled charging channels.

Each slot can detect and manage an installed compatible battery separately.

This means both batteries do not necessarily need to have the same capacity or physical size.

For example, users may be able to charge a compatible 18650 battery in one slot while charging another supported cell in the second slot.

The independent design also allows the LCD to display charging information separately for each battery.

500mA × 2 Charging Output

The Nitecore D2 provides a maximum charging current of approximately 500mA per slot.

When two compatible batteries are installed, each bay can operate independently at up to 500mA.

This specification is important because the D2 should not be confused with newer or higher-output chargers offering 1A, 2A, or faster charging rates.

For this exact model, the correct core output specification to highlight is:

500mA × 2

Charging time depends on battery capacity, remaining charge, battery condition, and chemistry.

Nitecore D2 LCD Display

One of the defining features of the Nitecore D2 LCD Charger is its digital information display.

The LCD allows users to monitor the charging process instead of relying only on basic LED indicators.

Depending on the selected slot and charging stage, the display can provide information related to:

• Battery voltage
• Charging progress
• Charging current
• Selected battery slot
• Charging status
• Battery chemistry or charging mode

This makes it easier to understand what the charger is doing while each battery is installed.

Intelligent Automatic Battery Detection

The D2 is designed to automatically identify many supported rechargeable battery types and select an appropriate charging process.

When a compatible battery is inserted correctly, the charger analyzes the cell and begins the required charging sequence.

Certain battery types, particularly LiFePO4, may require the appropriate charging mode to be selected manually.

Always follow the battery manufacturer’s voltage and charging instructions rather than relying only on physical fit.

Nitecore D2 for 18650 Batteries

The Nitecore D2 18650 Charger is suitable for compatible rechargeable 18650 lithium-ion cells.

18650 batteries are among the most commonly searched battery formats associated with the D2.

The two-slot design allows up to two compatible 18650 batteries to be charged independently.

Users should inspect every battery before charging and avoid cells with damaged wraps, dents, leakage, corrosion, or other visible defects.

Compatible Li-Ion Battery Sizes

The Nitecore D2 supports a broad selection of cylindrical rechargeable lithium-ion battery sizes.

Common compatible formats include:

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

Physical fit alone does not guarantee compatibility. Battery chemistry and voltage must also meet the charger’s supported specifications.

Does the Nitecore D2 Charge 26650 Batteries?

Yes, compatible 26650 lithium-ion batteries are supported by the Nitecore D2.

Because 26650 cells are physically larger than 18650 batteries, make sure the battery sits correctly within the adjustable charging slot.

Does the Nitecore D2 Charge 21700 Batteries?

The original Nitecore D2 compatibility information does not normally list 21700 batteries among its supported sizes.

For that reason, this product should not be advertised as a 21700 charger unless the exact manufacturer documentation supplied with your unit specifically confirms compatibility.

Customers who primarily use 21700 cells should choose a charger that explicitly lists 21700 support.

Ni-MH and Ni-Cd Battery Compatibility

The Nitecore D2 is more versatile than a charger designed only for lithium-ion cells.

It also supports selected Ni-MH and Ni-Cd rechargeable batteries, including common formats such as:

AA
AAA
AAAA
C

The charger automatically applies an appropriate charging process for compatible cells.

Never attempt to recharge disposable alkaline batteries.

LiFePO4 Battery Charging

The D2 also supports compatible LiFePO4 rechargeable batteries.

LiFePO4 cells use a different charging voltage from standard 4.2V lithium-ion batteries, so the correct charging mode is essential.

Users should identify the chemistry printed on the battery before charging.

Do not select LiFePO4 mode for a standard lithium-ion battery or vice versa.

IMR Battery Support

Compatible IMR rechargeable batteries can also be charged with the Nitecore D2.

As with any rechargeable battery, confirm that the battery’s voltage and physical format are supported before inserting it into the charger.

How to Use the Nitecore D2 Charger

Connect the Nitecore D2 to a suitable power source.

Insert a compatible rechargeable battery into either charging slot while observing the positive and negative polarity markings.

The charger should detect the installed battery and begin the appropriate charging process.

Check the LCD display to confirm that the battery is recognized correctly.

If you are using a chemistry requiring manual mode selection, choose the correct charging mode according to the battery specification.

Allow the charger to complete the charging cycle.

Remove the charged batteries when finished and disconnect the charger when it is no longer required.

Correct Battery Polarity

Always install rechargeable batteries according to the polarity markings shown on the charging bays.

The positive and negative terminals must be positioned correctly.

The Nitecore D2 includes reverse-polarity protection, but this should be treated as a backup safety feature rather than an alternative to correct battery installation.

Automatic Charging Termination

The Nitecore D2 Smart Charger is designed to manage the charging process automatically.

When a compatible battery reaches the appropriate full-charge condition, the charger terminates or manages the charging process to help prevent continued uncontrolled charging.

Users should still avoid leaving rechargeable batteries charging unattended for unnecessarily long periods.

Reverse Polarity Protection

Reverse-polarity protection helps prevent normal charging when a battery is installed incorrectly.

If the charger does not recognize a battery, check its orientation before assuming the battery or charger is defective.

Temperature Monitoring

The D2 includes intelligent temperature-related monitoring as part of its charging system.

Charging rechargeable batteries in very hot, wet, or poorly ventilated environments should be avoided.

Place the charger on a stable, dry, non-flammable surface during operation.

Nitecore D2 Safety Features

The D2 combines several protection and monitoring functions, including automatic charging control, reverse-polarity protection, battery-status monitoring, and intelligent charging management.

These features help manage normal charging, but they cannot make a damaged battery safe.

Never charge a battery that is:

• Swollen
• Leaking
• Dented
• Corroded
• Excessively hot
• Missing or severely damaged insulation
• Showing signs of physical failure

How Long Does the Nitecore D2 Take to Charge?

Charging time varies according to the battery.

A higher-capacity battery generally takes longer to charge than a lower-capacity cell when both receive the same charging current.

Other factors include:

Battery capacity
Current battery voltage
Cell condition
Battery chemistry
Number of charging cycles
Charging temperature

Because the D2 operates at up to approximately 500mA per slot, it is not designed as a high-speed 2A charger.
