Maintenance and Storage
- Regular Charging: For optimal battery life, recharge batteries when they are low, rather than waiting for them to be completely depleted.
- Storage: Store batteries in their charging case or another suitable battery organizer in a cool, dry place away from direct sunlight and extreme temperatures. The magnetic closure of the imuto charging case helps keep batteries secure.
- Cleaning: Keep battery terminals and charger contacts clean and free of debris. Use a dry cloth to wipe them if necessary.
- Disposal: Do not dispose of batteries in household waste. Recycle them at an authorized battery recycling facility.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Batteries not charging (no green light) | Loose connection, faulty cable/adapter, battery inserted incorrectly. | Ensure the USB-C cable is securely connected to both the charger and power source. Check battery polarity. Try a different USB cable or power adapter. |
| Flashing red light on charger | Incompatible battery type, damaged battery, or overheating. | Ensure only imuto rechargeable lithium AA batteries are used. Remove the battery and allow it to cool down if overheating is suspected. If the issue persists, the battery may be defective. |
| Batteries not holding charge | Battery nearing end of life, or device is high-drain. | While batteries have a long cycle life, performance may degrade over time. Consider replacing older batteries. For high-drain devices, frequent recharging is normal. |
