6. Operation
6.1. Charging Function
Once batteries are correctly inserted and the charger is connected to a power source, the charger will automatically begin the charging process. The LC4 and LC8 chargers support mixed charging of AA and AAA batteries simultaneously.
- LC4 Charging Times: Fully charges 4 x AA 1.5V Li-ion batteries in approximately 1.7 hours. Fully charges 4 x AAA 1.5V Li-ion batteries in approximately 1.5 hours.
- LC8 Charging Times: Fully charges 8 x AA 1.5V Li-ion batteries in approximately 2.7 hours. Fully charges 8 x AAA 1.5V Li-ion batteries in approximately 1.5 hours.
6.2. 0V Activation Function
The charger is equipped with a 0V activation function. When an over-discharged battery is inserted, the charger will automatically detect and attempt to activate it, bringing it back to life if possible.
6.3. Battery LED Indicator
The LED indicator on the charger provides real-time status of the batteries:
- Flickering Green LED: Indicates the battery is currently charging or being activated.
- Solid Green LED: Indicates the battery is fully charged.
6.4. Multiple Protections (QC3.0 Adapter)
The XTAR QC3.0 adapter adopts high-precision hardware to efficiently avoid safety hazards. It provides multiple protections for safe charging:
- Over-voltage protection
- Over-current protection
- Over-temperature protection
- Over-load protection
- Short-circuit protection
- Electrostatic prevention
7. Maintenance
- Keep the charger clean and free from dust and debris.
- Store the charger in a dry place, away from direct sunlight and extreme temperatures.
- Do not use harsh chemicals or abrasive cleaners on the charger. Use a soft, dry cloth for cleaning.
- When not in use, disconnect the charger from the power source.
8. Troubleshooting
- Charger not working: Ensure the USB cable is securely connected to both the charger and the power source. Verify the power source is active.
- Slow charging: If the power supply is insufficient (e.g., using a low-power USB port), the charger may automatically reduce the charging current. Use a QC3.0 compatible adapter or a 5V 2A/3A adapter for optimal performance.
- LED not indicating: Check if the battery is inserted correctly with the correct polarity. If the battery is severely over-discharged, it might take some time for the 0V activation function to initiate, or the battery might be beyond recovery.
- Charger feels warm: It is normal for the charger to feel slightly warm during operation. If it becomes excessively hot, disconnect it immediately and contact support.
9. User Tips
