3. Operating Instructions
3.1 Battery Insertion
Insert the fully charged imuto AA lithium batteries into your compatible devices, observing the correct polarity markings (+/-).
3.2 Constant Voltage Output
These 1.5V rechargeable AA lithium batteries deliver a consistent and stable 1.5V voltage output throughout their discharge cycle. This provides stronger energy output compared to 1.2V NiMH batteries, making them suitable for a wider range of devices, especially high-drain electronics.

3.3 Versatile Applications
The 2500mWh capacity and constant 1.5V output make these batteries ideal for various continuous high-drain devices, including:
- Video doorbells
- Security cameras
- Trail cameras
- Smoke detectors
- Smart locks
- Solar lights
- Toy cars
- Gaming controllers
- Remote controls
- Clocks
- Photographic lighting
- Other home and personal care devices

4.3 Charging Case for Storage and Protection
The charging case features a magnetic closure and independent battery slots, serving as both a fast charger and a storage box. It protects batteries from moisture, dust, pressure, and splashes, ensuring safety and easy portability.
4.4 Over-Discharged Battery Re-activation
The smart charging case includes a microcurrent function that can identify and reactivate excessively discharged batteries, restoring them to usable condition.
5. Safety Information
The imuto AA lithium batteries and charger are designed with multiple protection features and adhere to safety standards.
5.1 Built-in Protections
The system incorporates safeguards against:
- Over-charging
- Over-discharging
- Over-heating
- Over-current
- Over-voltage

5.2 Environmental Considerations
The batteries utilize CBPI sealing technology for excellent leak-proof performance and improved space utilization. They are manufactured without harmful substances such as lead, mercury, and cadmium, prioritizing environmental and user safety.
5.3 Operating Temperature Range
The batteries are designed to operate reliably across a wide temperature range:
- Charging: 32°F to 113°F (0°C to 45°C)
- Discharge: -40°F to 140°F (-40°C to 60°C)

6. Troubleshooting
6.1 Charging Issues
- Batteries not charging (LED blinking red): This indicates a battery failure. Remove the faulty battery and try charging others. If multiple batteries show this, contact support.
- Charger not working (No LED light): Ensure the Type-C cable is securely connected to both the charger and a functional 5V/3A power adapter. Try a different cable or adapter if available.
- Slow charging: Verify that your power adapter provides 5V/3A output for optimal fast charging. Lower output adapters will result in slower charging times.
6.2 Device Compatibility
- Device not powering on: Ensure batteries are fully charged and inserted with correct polarity. Some very low-power devices might not be compatible with 1.5V lithium-ion batteries if they specifically require 1.2V NiMH or alkaline.
