I have also had occasion to remove all four AAA batteries from my calc at
one time, and leave it that way for a while... The lithium does work at
that time.
As for turning the calc off from CShell and removing the batteries, Keith
has worked it out to have the calc turn off with the _EXACT_ same routine
the calc uses... I know that for sure, because we actually let the TI-ROM
turn the calc off... This should then allow for the same kind of
treatment of the batteries that you get if you turn the calc off in the
TI-OS and pull the batteries...
