I wonder whether I'll better do that outside the computer though.
After all, the Coulomb counter in the battery does not care much
whether it is attached to a computer querying it or not.

I did want to reboot it into normal operation in order to allow the
nightly backup to run. I simply ran out of time waiting for the
battery to drain completely. Anyway, at a voltage level of < 9.0 V,
it wouldn't have lasted for another quarter of an hour. (Worst case
cutoff level for a LiIon cell is around 2.7 V.)

Never trust an operating system you don't have sources for. ;-)
