2. Sicherheitshinweise
- Use only the provided 12V 5A power adapter. Using an incorrect adapter may damage the charger or batteries.
- Nicht wiederaufladbare Batterien dürfen nicht geladen werden. Dies kann zu Explosionen, Bersten oder Auslaufen führen und Personen- oder Sachschäden verursachen.
- Achten Sie beim Einlegen der Batterien in die Ladegeräte auf die richtige Polarität (+/-).
- Das Ladegerät darf weder Wasser, hoher Luftfeuchtigkeit noch extremen Temperaturen ausgesetzt werden.
- Halten Sie das Ladegerät während des Betriebs von brennbaren Materialien fern.
- Das Ladegerät darf nicht zerlegt oder verändert werden. Alle Wartungsarbeiten dürfen nur von qualifiziertem Fachpersonal durchgeführt werden.
- The charger features independent temperature detection for each slot. If a battery's temperature reaches 65°C (149°F), the charger will automatically reduce the charging current. If the temperature continues to rise, the current will drop to the lowest setting (250mA).
- Test results for internal resistance (mR) are for reference only and should not be used for commercial or official proof.

6. Bedienungsanleitung
The Lii-600 charger features two main touch buttons: "MODE" and "CURRENT".
- MODE-Taste: Used to select the operating mode (CHARGE, TEST, DISCHARGE, REPAIR). Press and hold for 3 seconds to enter mode selection.
- AKTUELL-Schaltfläche: Used to manually select the charging or discharging current.
- SLOTS Buttons (1, 2, 3, 4): Used to select individual battery slots for specific settings.
6.1. CHARGE Mode
This is the default mode for charging batteries.
- Insert the battery. The charger will automatically detect the battery type and enter CHARGE mode.
- The charger will automatically distribute the charging current based on battery resistance.
- To manually select the charging current (250mA, 500mA, 1000mA, 1500mA, 2000mA, 2500mA, 3000mA), press the "CURRENT" button repeatedly within 8 seconds of inserting the battery or selecting the slot.
- The charging process will begin. The LCD will display real-time charging status.
6.2. TEST Mode (Capacity Test)
This mode measures the actual capacity of the battery. It involves a full discharge followed by a full charge.
- Legen Sie die Batterie ein.
- Press and hold the "MODE" button for 3 seconds to enter mode selection.
- Press "MODE" repeatedly until "TEST" is displayed.
- Press the "CURRENT" button to select the desired charging current for the test cycle.
- The charger will first fully discharge the battery, then fully charge it, and finally display the measured capacity. This process takes time.
6.3. DISCHARGE Mode
In diesem Modus wird der Akku auf eine sichere niedrige Spannung entladen.tage.
- Legen Sie die Batterie ein.
- Press and hold the "MODE" button for 3 seconds to enter mode selection.
- Press "MODE" repeatedly until "DISCHARGE" is displayed.
- Press the "CURRENT" button to select the desired discharge current.
- If charging current is 250mA, discharge current is 250mA.
- If charging current is 500mA or 1000mA, discharge current is 500mA.
- If charging current is 1500mA, 2000mA, 2500mA, 3000mA, discharge current is 750mA.
- For Ni-MH batteries, discharge current is limited to 250mA or 500mA.
- The battery will begin discharging.
6.4. REPAIR Mode
