- Battery Contacts: If batteries are rejected frequently, check if their surfaces are dirty or corroded. Clean battery contacts with a clean, dry cloth or a cotton swab dipped in rubbing alcohol.
- Storage: When not in use for extended periods, store the charger in a cool, dry place away from direct sunlight and extreme temperatures.
Troubleshooting
This section addresses common issues you might encounter with your Ostation X charger.
Indicator Light Meanings
The LED indicator ring provides crucial information about the device's current status:

Image: Visual guide to the different colors of the LED indicator ring.
- White: Ready for loading cells.
- Green: Preparing for charging.
- Blue: Charging in progress.
- Red: Malfunction detected (e.g., faulty battery).
- Yellow: Incompatible adapter connected.
Common Issues and Solutions
- Charger not working with adapter / Indicator is Yellow:
Ensure you are using a PD-compatible charger that outputs at least 12V & 1.5A. The device will not function correctly with an incompatible power source.

Image: Illustration emphasizing the requirement for a 12V & 1.5A PD-compatible adapter.
- Last 20% of charge takes longer:
This is normal behavior. To protect battery health and extend lifespan, the charging speed slows down after reaching 80% capacity.
- Noise in fast charging mode:
The cooling fan activates in fast-charging mode to dissipate heat. This is normal. If the noise is disruptive, consider placing the charger in a less sensitive area or setting a non-charging time in the app.

Image: Explanations for slower charging at high capacity and fan operation during fast charging.
- Good cells in the invalid bin:
The battery identification accuracy is 99.5%. If a seemingly good battery is rejected, dirty or corroded surfaces might be the cause. Clean the battery contacts and re-insert it. If the issue persists, the battery might be genuinely faulty.

- Is the APP required to use the Ostation X?
While the basic charging function can operate without the app, the app is required to monitor charging status, control advanced features, and receive important firmware updates for the Ostation X AA. It is highly recommended for a complete user experience.
