I understand that, but some electronics want 12 volts, not 11 or 13, 12.
And bad batteries won't hold any charge, nothing. Like a frozen one.
While were at it, electronic cars should not be running when you give someone a boost, jumps in voltage or a dead short could fry YOUR computer or lots of other stuff. Tow trucks have separate isolated batteries for boosting because of this.
