Well, it was at least entertaining. I wonder if I kept the dead battery
pack from my drill...

Have you considered that the trouble may BE that "the charger puts out
7.5v". I'd check it again. If it is only charging a 12v battery to 7.5
v, you would indeed have a drill acting like it was feeling poorly.
If you have no other chargers, (which seems unlikely on this list) a car
battery should be safe. Putting 12v across a 12v battery should be safe
for the simple reason that that's what the charger is supposed to do.
It's not like the 31v the video uses.
