5. Betjeningsvejledning
5.1 Opladningsproces
- Once batteries are inserted, the LCD display will activate and show the charging status for each slot independently.
- The charger utilizes a CC-CV (Constant Current - Constant Voltage) charging mode for efficient and safe charging.
- Charging speed is approximately 1000mA per slot. For example, a 2500mAh 18650 battery may take 2-3 hours, and a 5000mAh 21700 battery may take 5-6 hours.

5.2 LCD-displayindikatorer
The LCD screen provides a visual representation of the battery charge level:
- 0-25 %: First segment of the battery icon is filled.
- 25-50 %: Second segment of the battery icon is filled.
- 50-75 %: Third segment of the battery icon is filled.
- 75-100 %: Fourth segment of the battery icon is filled.
- 100 %: All segments of the battery icon are filled, indicating a full charge.
- Abnormal Charging/Battery Failure: The battery icon will flash, indicating an issue.
Image 5.2: The LCD display clearly indicates the charging progress from 0% to 100% and signals battery failure with a flashing icon.
5.3 0V/Low-Voltage-aktivering
The charger can activate 1.9-2.8V (±0.1V tolerance) batteries with 0V and low-voltage activation. This feature helps to restore over-discharged lithium batteries, ensuring their lifespan and safety. This function is primarily applicable to lithium batteries equipped with protection boards.
