Does My Garmin Dash Cam have an Internal Battery?

The Garmin Dash Cam™ Mini 3 | Garmin Dash Cam™ Mini 2| Garmin Dash Cam™ Mini| and Garmin Dash Cam™ Tandem driving recorders do not have an internal battery.  Instead, they have a super-capacitor that gives sufficient time for the Garmin Dash Cam to properly power down when external power is removed from the device.
