question mark on battery icon

Could you post a picture/screenshot. Is the icon for the Edge battery or the lights?

magic1o9o7o2 thanks for your post.
This symbol does not impact battery performance. Was the Edge 850 battery removed or replaced? 

Please contact the Garmin support office for your region to notify them of the concern and discuss service options: https://support.garmin.com

It s the original battery, i bought the edge 850 two months ago

Thanks for confirming. Do I have your consent to reach out to you via email?
I'd like to get you in contact with our regional support offices to consider options for evaluating the Edge.

Cargotourercommuter are you experiencing this behavior for your device?

No, just trying to avoid it of possible. It seems like such a strange thing
