5. Setup
- Unpack the Charger: Carefully remove the ABSINA Battery Charger X4 from its packaging. Inspect it for any signs of damage.
- Choose a Location: Place the charger on a flat, stable, and non-flammable surface. Ensure the area is well-ventilated and away from direct sunlight, heat sources, or moisture.
- Connect to Power: Plug the charger directly into a standard AC power outlet (100-240V AC, 50-60Hz). The charger is designed for worldwide use.
6. Operating Instructions
Follow these steps to charge your rechargeable batteries:
- Insert Batteries: Insert 1 to 4 AA or AAA NiMH/NiCd batteries, or 1 to 2 9V NiMH/NiCd batteries into the corresponding charging slots. Ensure correct polarity (+ and -) as indicated on the charger and batteries.
- Automatic Charging Start: The charger will automatically detect the battery type and begin the charging process. The LED indicator for each slot will illuminate green, indicating active charging. If a red LED appears, the battery is defective (refer to Troubleshooting).
- Charging Status:
- Green LED (Solid): Battery is charging.
- Green LED (Solid, after charging): Battery is fully charged and the charger has switched to trickle charge.
- Red LED (Solid): Defective battery detected. Remove the battery.
- Charging Time: Charging time varies depending on the battery capacity and discharge level. For typical AA batteries (2500mAh), charging can take approximately 2 hours. Refer to the "Charging Time Table" in the Specifications section for estimates.
- Remove Batteries: Once the LED indicator for a battery turns solid green (indicating full charge), you can remove the battery. The charger will automatically stop charging that specific slot.

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not working / No LEDs light up. | No power supply. | Ensure the charger is securely plugged into a live power outlet. |
| Red LED lights up for a battery. | Defective battery or incorrect battery type. | Remove the battery. This charger is only for NiMH/NiCd rechargeable batteries. If it's a NiMH/NiCd battery, it may be permanently damaged and needs replacement. |
| Batteries do not charge fully or take too long. | Batteries are old, deeply discharged, or have reduced capacity. | The charger has a repair mode for deeply discharged batteries. Allow it to run. If issues persist, the batteries may need replacement. Ensure batteries are NiMH/NiCd. |
| Charger feels warm during operation. | Normal operation. | It is normal for the charger and batteries to become slightly warm during charging. Ensure adequate ventilation. If it becomes excessively hot, unplug immediately and contact support. |
