perhaps
but quite a bit of current

Yep
The current theoretically needed to kill a human is only in the ~5mA reigon, and a car battery charger puts out waaaay more than that. Fortunately, the "clench hands and jerk" reaction meant that I released the clips again and pulled them free.

If the 5mA is true,
At 12v your body would need to have a resistance of 2400 ohms or less.

Now the car battery torture scenes are ruined for me.

Apparently...
You need a current of something like 70mA - 700mA to trigger ventricular fibrillation. Anything over 1A will start causing burns and cellular damage. This is for externally applied electrical currents. On the other hand, it only needs 10µA applied directly to the heart to start it a-fluttering.
