Total crap. There is no pint in having a 150A capable alternator to do THAT

You are forgetting the internal resistance of the battery. The fact is
that the most charge a car will give a flat battery is around 30A, it it
drops off very rapidly. The high alternator output is to support
accessories.


The internal impedance of a battery is a bit of a red herring. Given they
can deliver perhaps 600 amps at starting.
