Nitecore D2 Smart Charger Brugermanual

1. Introduktion

The Nitecore D2 is an advanced universal smart charger compatible with nearly all cylindrical rechargeable batteries. It automatically detects Li-ion, IMR, LiFePO4, Ni-MH, and Ni-Cd batteries, and through intelligent circuitry, selects the optimal charging mode (CC, CV, and dV/dt). The integrated LCD panel clearly displays charging parameters and progress. The D2 features two independently controlled charging slots, allowing for simultaneous charging of different battery types.

2. Sikkerhedsoplysninger

• Use the charger only with compatible rechargeable batteries as listed in the specifications. Attempting to charge non-rechargeable batteries may cause explosion, rupture, or leakage, resulting in property damage and/or personal injury.
• Ensure correct battery polarity (+/-) when inserting batteries into the charging slots. The charger features reverse polarity protection.
• Efterlad ikke opladningsbatterier uden opsyn.
• Keep the charger away from water, high humidity, and extreme temperatures.
• The charger is constructed from durable ABS (fire retardant/flame resistant) material for enhanced safety.
• Opladeren må ikke skilles ad eller modificeres.
• Tag opladeren ud af strømkilden, når den ikke er i brug.

3. Pakkens indhold

5. Opsætning

1. Tilslut strøm: Plug the AC power cord into the charger and then into a wall outlet, or connect the 12V DC car power cord to the charger and then to your vehicle's 12V DC socket. The charger will perform a self-test, and the LCD screen will illuminate.
2. Første visning: When no batteries are inserted, the LCD will display "null".

6. Betjeningsvejledning

6.1 Isætning af batterier

Insert one or two rechargeable batteries into the D2's charging slots. The charger will automatically identify the battery type (Li-ion, IMR, Ni-MH, Ni-Cd) and begin charging. For LiFePO4 batteries, manual selection is required (see section 6.4).

This image illustrates the compact design of the Nitecore D2 charger and its ability to accommodate two batteries of varying sizes and chemistries simultaneously, including Li-ion, IMR, LiFePO4, Ni-MH, and Ni-Cd.

6.2 Forståelse af LCD-skærmen

The integrated LCD panel provides real-time information about the charging process:

• Opladningsstatus: Displays the current charge level with a bar graph.
• Batteritype: Indicates the detected battery chemistry (e.g., Li-ion, Ni-MH).
• Opladningstilstand: Shows the active charging mode (CC, CV, or -dV/dt).
• Voltage: Viser den aktuelle batterivolumentage.
• Strøm: Shows the charging current in mA.
• Opladningstid: Angiver den forløbne opladningsvarighed.

Use the two side buttons to cycle through information for each slot or to select specific battery types and charging parameters.

This image demonstrates the charger's intelligent auto-detect function, showing how it identifies battery types and selects appropriate charging modes like Constant Current (CC), Constant Voltage (CV), and -dV/dt detection for Ni-MH/Ni-Cd batteries.

6.3 Opladningsproces

Once a battery is inserted, the charger will automatically detect its type and begin charging. The LCD will show the progress. Charging stops automatically when complete.

6.4 Manual LiFePO4 Selection

For LiFePO4 batteries, the charger requires manual selection. After inserting a LiFePO4 battery, press the side button corresponding to that slot to cycle through the battery types until "LiFePO4" is displayed. The charger will then proceed with the appropriate charging cycle.

6.5 Using AA to D Battery Converter Spacers

The included EdisonBright AA to D battery converter spacers allow you to use rechargeable AA batteries in devices designed for D-sized batteries. Simply insert an AA battery into the spacer, then place the spacer into the D-sized battery compartment of your device. These spacers do not affect the charging process of the AA batteries in the Nitecore D2 charger.

7. Vedligeholdelse

• Rengør oplader- og batterikontakterne regelmæssigt med en tør, blød klud.
• Opbevar opladeren på et køligt, tørt sted, når den ikke er i brug.
• Avoid exposing the charger to direct sunlight or extreme temperatures.

8. Fejlfinding

• Opladeren tænder ikke: Ensure the power cord is securely connected to both the charger and the power outlet/source. Check if the outlet is functional.
• Batteri oplades ikke: Verify that the battery is inserted with correct polarity. Ensure the battery is a compatible rechargeable type. If the battery is severely over-discharged, it may not be recognized immediately; try reinserting.
• LCD display shows "null": This indicates no battery is detected in the slot. Ensure the battery is properly seated and making contact.
• Overophedning: The charger has temperature monitoring. If the charger or battery becomes excessively hot, discontinue use and allow it to cool. Ensure proper ventilation around the charger.
