What's your version of "quick"?

Without the battery, I'd expect all starts to be cold.  There may be enough 
capacitance in there to hold for a few seconds.

This brings up the opportunity for an interesting bug.  One of the things 
that gets saved is the offset between GPS time and UTC.  If you are running 
in NMEA mode, there is no way for the device to say "I know where I'm located 
and the GPS time, but I don't know the UTC offset."  It can either wait or 
give you the time that may be wrong.

My first attempt with one of Gary's PPS over USB units was off by a second.  
That would make sense if the firmware had a compiled in default from before 
the last leap second.
