Problem
The Corsair Harpoon Wireless Mouse runs on a rechargeable battery. If you don’t know how to check the charge level, the mouse may unexpectedly power off during use, especially in wireless or Bluetooth mode.
Solution
You can check the battery level of the Corsair Harpoon Wireless Mouse through iCUE software, onboard LED indicators, or system notifications.
Step-by-step instructions
Method 1: Using iCUE software (recommended)
- Connect the mouse to your PC (via USB cable, wireless dongle, or Bluetooth).
- Open the Corsair iCUE software.
- Select the Harpoon Wireless Mouse from the device list.
- Look for the battery percentage indicator on the device dashboard.
- Monitor charge levels while gaming — iCUE updates in real time.
Method 2: Using onboard LED indicator
6. Check the LED light near the scroll wheel or DPI button (varies by model).
- Green = High battery
- Yellow = Medium battery
- Red = Low battery
- If the LED flashes red, the battery is critically low and needs charging.
Method 3: System notifications (Windows)
8. On Windows PCs, connect the mouse via Bluetooth.
9. Go to Settings > Devices > Bluetooth & other devices.
10. Select Corsair Harpoon Wireless to view its battery level (if supported by the system).
Optional methods or tools
- Wired mode: Connect via USB to continue playing while charging.
- Custom iCUE alerts: Set notifications when battery drops below a chosen level.
Best practices or tips
- Check the battery before long gaming sessions to avoid interruptions.
- Keep the USB charging cable nearby for quick access.
- Use 2.4GHz dongle mode instead of Bluetooth if you want better battery efficiency and lower latency.
- Fully charge the mouse periodically to keep the battery healthy.
