williamwright was thinking very hard :
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.
Correct! I have taken the trouble to actually measure it and have
seen 20 to maybe 30amps delivered by a 130amp alternator, into a near
flat battery. That level of charge current rapidly declines as the
flat battery gains in voltage.
I have battery chargers that will dump full permitted current into a
battery until it is =99% full.
Yes, intelligent chargers with a temperature sensor strapped to the side
of the battery.

No Bill. They dont have that.
Wrong again.
