The system ran for 7 hours and 50 minutes. However the OPUS did NOT leave me enough power to crank the engine. So it didn't turn it off soon enough. Ohh well. Don;t think I would ever leave it that long anway.,
If I can run full power for basically 8 hours, I should be able to run standby for a LONG time. So I am going to use that from now on to get a super fast boot time.
The saga has ended!
