I posted my best advice to a guy who admittedly claimed no knowledge about cars. You and others came into this thread to be pricks, plain and simple, your posts sole purpose's was to be pricks, not help anyone, just to be pricks!

Prove I'm wrong, what basic laws of physics am I arguing ?
When hooking up booster cables between two cars, you are adding the second battery to a PARALLEL circuit. Positive to positive, negative to chassis (which is the same as negative to negative because cars use a negative ground to the chassis from the battery completing the circuit)

When two or more battery's of the same voltage in a parallel circuit the same voltage is present in each branch.

I suppose there could exist the opportunity for load dumping if a battery somehow gets disconnected from the alternator. The massive increase in current would spike the voltage but probably not that big because the resistivity of the dead battery would be low.

V=I*R

I would be much more afraid of a dead short while driving normally but thankfully, most modern alternators can deal with it and semi-conductors are protected.

I have no idea how anyone would create a dead short in the system except if they laid a wrench across the battery touching both posts.

Can't really for see either situations where this would happen if you follow basic boosting instructions.
