Ultegra di2 6870 and the charger that came with it
It is internally routed
The seat was removed and wire disconnected. The handlebar was removed but not disconnected.

I have that charger. The light goes out when it is charged. There is also an error status light, so if something is wrong, it flashes. So if you saw nothing, presumably your battery is charged and healthy.
