5. Enstalasyon
- Konekte pouvwa: Connect the provided USB-C cable to the charger's input port and plug the other end into a compatible USB power adapter (not included, 5V/2A recommended). The LCD screen will illuminate.
- Mete pil: Carefully insert 1 to 4 rechargeable AA or AAA batteries into the charger slots, ensuring correct polarity (+ and - ends match the markings on the charger).
- Deteksyon otomatik: The charger will automatically detect the battery type (Li-ion 1.5V or Ni-MH 1.2V) and display the current status on the LCD screen.
6. Operasyon Enstriksyon
6.1. Chaje pil
- After inserting batteries, the charger will begin charging automatically.
- The LCD screen will show the charging progress for each slot.
- Charging time for rechargeable lithium AA/AAA batteries is approximately 1.5 hours.
- Once charging is complete, the LCD will display "Done" for the respective slot.
- Remove batteries promptly after charging is complete.
6.2. Refresh Mode (for Ni-MH Batteries)
The Refresh Mode is designed to maximize the capacity of older or frequently used Ni-MH batteries by fully discharging and then recharging them. This process can help reduce memory effect.
- DisCHG Mode: A daily and quick refresh, ideal for batteries that are not too old.
- Rafrechir mòd: A deep and intelligent refresh, suitable for older or frequently used batteries.

6.3. Repair Mode (for 1.2V Ni-MH Batteries)
The Repair Mode uses micro-current activation technology to safely recover over-discharged 1.2V Ni-MH batteries, potentially saving them from being discarded.
- Insert an over-discharged 1.2V Ni-MH battery into a slot.
- The charger will attempt to activate the battery using a low current.
- If successful, the charger will proceed with normal charging. If not, "Err" will be displayed.
