I have never seen a car with a battery for the electric window. The electric windows use the main car battery. If your electric window does not function properly, there is some other reason for it's erratic behavior. ie: intermittent short, faulty switch (my guess), faulty window motor, etc, etc.
If the battery is defective get a new battery. If you just left something on and ran it down, charge the battery and keep going.
The electric shaver appears to be capapble of operating on both mains electricity and the internal battery. Mains electricity will keep the battery recharged but if you use the battery to run the shaver then soon or latter the battery will run out of elctricity. Battery Low means No Working Shaver.

Yes, there is probably a drainage to keep the clock going.
you have to hold the battery cable or the nut behind it to keep it from turning with the nut you are removing.
