Frequently Asked Questions

Why is my battery flashing purple?
Flashing purple indicates a general error. Try resetting your battery by disconnecting it and pressing the button 5 times quickly. If the issue persists, contact support.
How do I know when my battery is fully charged?
When charging, the LED will pulse green. Once fully charged, it becomes a solid green light. Unplug to preserve battery life.
What does solid blue mean?
Solid blue indicates your battery is successfully connected to your device. If you see this but your device isn't working, try reconnecting.
Can I customize the LED colors?
The Mfused Smart Battery has preset colors that cannot be customized. They're designed to give you clear, consistent information about your battery status.
Why is my battery not showing any lights?
If no lights appear when pressing the button, the battery may be completely drained. Connect to a charger for at least 15 minutes. If still no response, try a different charging cable.
What's the difference between pulsing and flashing?
Pulsing means a slow, smooth fade in and out (usually for charging). Flashing means rapid on/off (usually for errors or pairing mode). Both are shown in our guide above.
