The reason for the high current drain is that all the basic electronics (display, all the ECUs, etc.) are powered from the 12-V battery. See my measurements in the thread "Disconnecting the 12-v battery."

Both D and Lantern batteries would have no problem producing 10 amps for an hour. I suspect even the smaller ones could do it for the few seconds it takes to boot the computer and close the inverter contactor.
