4. Maintenance and Care
4.1 Recharging
The XTAR AAA LR 900 battery supports over 800 recharge cycles, offering long-term savings and reduced waste. Always use a compatible USB-C cable and power source for recharging.
4.2 Storage
Store batteries in a cool, dry place with a temperature range of -10°C to 45°C. For prolonged storage, it is advisable to store them partially charged (around 50%). Use the provided battery case for safe storage.
4.3 Safety Precautions
- Do not disassemble, short circuit, or expose to excessive heat.
- Keep batteries out of reach of children.
- Avoid physical damage to the battery.
- Do not mix with non-rechargeable batteries or batteries of different types/brands.
5. Troubleshooting
5.1 Device Not Powering On
- Ensure batteries are fully charged.
- Verify correct polarity (+/-) during installation.
- Check if the device itself is functioning correctly with other known good batteries.
5.2 Charging Issues
- Ensure the USB-C cable is securely connected to both the battery and the power source.
- Try a different USB-C cable or power adapter to rule out cable/adapter issues.
- Confirm the power source is active and providing sufficient power.
5.3 Sudden Power Outage
Unlike some conventional lithium batteries, the XTAR AAA LR 900 features a smarter discharge curve that provides a gradual voltage decline similar to alkaline batteries. This helps in more accurate battery level indication and reduces the risk of sudden power outages in devices. If a device still experiences sudden power loss, it may indicate the battery is fully depleted or the device itself has specific power requirements.
