Raspbian 2013-07-26 snapshot
Sandisk 64GB Class 10 SD card
Component video cable plugged (to a tv)
1 USB mouse directly into the RPI
1 USB keyboard directly into the RPI
Ethernet cable into a switch
NO hdmi / NO sound / NO cmos camera
software: Xwindows server (the graphical interface) + a top command
System load was nothing ( 0.02/0.05 @ 10m )
Delivers: 2 USB x 5V 3A (the 3A are shared, either 1x3A or 2x1.5A)
Battery was charged fully (obviously!
The Raspberry Pi managed to run for 17 hours and 12 minutes.
It shut down cleanly and without any stability problems.
The system was running fine until the last second.
Finally 10,000/17.20 = 581mAh
This RPI has been using *on average* 581mA
