3. Operating Instructions
Once batteries are inserted and the charger is connected to a power source, the intelligent LED display will activate to show the charging status.
Understanding the LED Display:
The charger features an LED display for each charging channel (CH1 and CH2). This display indicates the current charging status and the approximate battery capacity.

Image: The Kastar LTD2 charger's LED display, illustrating how charging status is shown for channels CH1 and CH2. Below the image, a table details the indicator status (battery icon with bars), corresponding power ratio (e.g., 6%-25%, 76%-100%), and a description of how many LEDs are illuminated (e.g., One LED on, Four LED on).
| Indicator Status | Power Ratio | Statements |
|---|---|---|
| (Empty battery icon) | No power | No power |
| (Battery icon with 1 bar) | 6%---25% | One LED on |
| (Battery icon with 2 bars) | 26%---50% | Two LED on |
| (Battery icon with 3 bars) | 51%---75% | Three LED on |
| (Battery icon with 4 bars) | 76%---100% | Four LED on |
When the battery is fully charged, all four LED segments will be illuminated, and the charging process will automatically stop to prevent overcharging.
4. Maintenance and Care
Proper maintenance ensures the longevity and optimal performance of your charger.
- Cleaning: Disconnect the charger from the power source before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or solvents.

5. Troubleshooting
If you encounter issues with your charger, refer to the following common problems and solutions:
- Charger not powering on / LED display off:
- Ensure the USB cable is securely connected to both the charger and the power source.
- Verify that the power source (e.g., USB port, AC adapter) is functional and providing power.
- Try a different USB cable or power source.
- Battery not charging / LED not indicating charge:
- Check that the battery is correctly inserted into the charging slot with contacts aligned.
- Ensure the battery is compatible with the charger (Ordro NP-180/NP180).
- The battery might be completely depleted. Allow it to charge for a few minutes to see if the indicator activates.
- The battery may be faulty. Try charging a different battery if available.
- Slow charging:
- Ensure your power source provides sufficient current (recommended 5V 2-3A). Lower current sources will result in slower charging.
- Avoid using excessively long or low-quality USB cables, which can reduce charging efficiency.
