They may claim it works this way, but I have frequently resorted to
removing the grip when the battery depleted indicator comes on and
either run with the in-camera batteries or switch the batteries from the
grip to the body, and get quite a few more pics out of them. So they
are not measuring something correctly.

I dunno if this has been discussed already but thought I should share anyway.
According to Pentax Japan (ist-D FAQ) it uses both in camera and in
grip batteries more or less at the same time.
In fact it periodicaly checks the voltage of both batteries group and
uses the one with higher voltage (or was it current?, not sure...).
What it means is this: if your D shows a low battery indicator (and
they are low indeed) then BOTH in camera and in grip batteries are
depleted.
Hope it helps someone...
