No Mister Moron, that's not what I said. As somebody who claims to be possibly the smartest human being alive AND works for the biggest and best cell phone company in the entire world, you should have a grasp on this. Even when batteries are properly recharged and maintained, THEY STILL WEAR OUT. When a battery wears out, no amount of charging will make it good again, all you can do is replace it.

I claimed to be making them a delivery while working at a small retail center you Imbasil.

Actually VWHobo, while you are correct that the battery does supply current for starting and extraordinary loads, the alternator is the primary power source.

Why you question? Well I'm glad you asked. In simple terms current flows due to potential difference= voltage in this case. The alternator generates a voltage higher than the battery thus electron flow is biased towards the alternator from both the battery and the other electrical loads. If the duty on the alternator causes the output to drop below the battery voltage, the battery will take the lion's share of the load. See Kirchoff's Law for more thrilling insights into current flow.

But now a question ... do you consider current flow from +ve or to +ve? Some people have major issues with the convention due to the obvious physical contradiction.

An automotive storage battery has 3 main functions.

1.provides voltage and serves as a source of current for starting,lighting and ignition.
2.It acts as a voltage stabalizer for the entire electrical system of the vehicle
3.it provides current whenever the vehicles electrical demands exceed the output of the charging system

laaa dee daa

and there are 3 theories as to direction of cureent flow
1.conventional theory: which states cureent flows from positive to negative
2.electron flow theory: which statescurrent moves from negative to positive
3.hole flow theory:which basicall says something is moving in both directions

a theory is not a fact it is a concept that is yet to be proved wrong or right, so basically only one theory is right and the rest are wrong, that much we know. to make it easy current flows from a point of higher potential(voltage) to a point of lower potential(voltage).

During cranking the battery supplies all the vehicles electrical power, but once the vehicle is running the charging system is responsible for producing enough energy to meet the demands off all the loads in the electrical system while charging the battery at the same time

they all work hand in hand, you cant have one without the other, at least not for very long. I did not state if anyone is wrong or right here im just stating the facts

... or more appropriately, something flows in one direction, and "nothing" flows in the other....

now is it really "nothing" there can never be nothing so what would it be?

...
can an electron exist without a hole?
can a hole exist without an electron?

nothin, I'd say... the local electron would just effectively become a +ve ion for that brief period of time.

.... most of everything is nothing after all.

Well I guess I'm a student of the seventies technology so I'll have to stick with negatively charged electrons being attracted to positive region holes left by preceding electrons moving to other holes, etc. Polygamous little blighters aren't they?

... but you still didn't answer my question... which way does it go?

Well conventional flow is imaginary and flows +ve to -ve, whereas electron flow is actual and flows -ve to +ve.

People have trouble with electron flow theory because they have been brought up to think that high pressure forces things into a low pressure, therefore +12V must be high pressure voltage that squirts to the low voltage side..
