Yes, any output over and above the lights needs (when they are on) goes to the battery.
I don't think the battery rejects small output, but with the lights on and speed slow, a devices needs can be greater than whats going into the cache battery.
In this case, the cache battery drains and then so does the device internal battery.
I've not ever run completely out of device power but have seriously depleted my cache battery to the point of the device battery starting to drain.
Not really an issue on tour as I don't tend to tour in the dark due to the impossibility of spotting a suitable camp site in the dark.

The larger Garmin Edge models usually have in excess of more hours cache internally than one wold normally drain in an evening riding. The claimed 15-18 hours is in my experience more akin to half that but thats usually still plenty.
