" I am not about to argue the laws of physics, but in the real world it doesn't work your way"

Well yes, as a matter of fact, it does.

That carbon load tester, battery cell size....all of that......is governed by the laws of physics & basic electrical theory.

So lets start this conversation again.

Double the voltage, double the current.

Agree or disagree?

Double the current & double the voltage & the power quadruples. (under load)

Agree or disagree?

There's plenty in this world I do not understand.

That does not mean I'm stupid. Refusing to learn, however, does make me stupid.
And clearly, YOU do not understand basic electricity. And that's fine. There are 4 of us telling you that you are WRONG. The attached link will prove that you are WRONG if you do not want to take our word for it. Four of us are willing to help you understand these basics, but if you want to pump up and tell us your 40 years of testing batteries disproves basic electrical theory, then you may continue to live in ignorance.

But just don't walk to far to the west....you could fall of the edge of the earth.

He must work where 36coupe did all his electrical research.

too bad the research material tyhey studdied was incorrect. ;)

OK, lets look at it another way. Go to the tractor battery charts. Look up the size (dimensions ) of a 6 volt 500 amp battery. Then look up the size (dimensions) of a 12 volt 1000 amp battery. If what you are saying is true, they should be the same. Please post the results so we all can see.

No Teddy - once again you digress. You are hung up on cell size and ultimate output capacity and stubbornly refuse to look at anything beyond that.

You are unwilling to acknowledge the fundamental electrical behavior of the starting circuit as a function of the voltage applied to the fixed resistance windings of a DC motor. And until you are willing to get beyond that point you are never going to really understand the basic physics of why the same motor spins the same engine faster at 12V than it does at 6V.
Physics is nothing more than a mathematical explanation of why things behave as they do in real life. The physics of DC motor control and operation has been well established and experimentally confirmed starting with Michael Faraday's early experiments (1821), Joseph Henry's invention of an oscillating motor in 1831, and William Sturgeons invention of the first real rotary (commutator) electric motor in 1832. The electrical principles they pioneered have been taught to engineers for nearly two centuries now and the result has been the development of a vast array of electric motors of all types that permeate our daily life.

Here is a simple lesson from the Physics Department at the University of Texas (JMOR's Alma Mater???) that explains current flow in a DC motor circuit. You don't need a PhD. in physics to understand it.

The Direct Current Motor

That physics is EXACTLY how it works in real life and I'm pretty sure you and your carbon pile have not proven it to be wrong.

OK, tnx to Albert Knowles, I now recall Teddy: " this is the same(teddy52food) joker that awhile back argued for days in support of a perpetual motion motion machine with output greater than its input. "

So, I think we are trying to teach a pig to sing; it just wastes our time & annoys the pig.

But, it is eye-opening to see such a public display of abject ignorance.

It's not the lack of basic electrical knowledge (we see that a lot) but the total & complete rejection of actually learning something that conflicts w/ his beliefs.

Maybe we shouldn't tell him where the sun goes at night......

No I don't agree with you. I just talked to a retired IH mechanic that agrees with me. Look at it this way. Take a 6 volt battery. It has 3 large cells. The same size 12 volt battery has 6 cells that are half as big as the ones in the 6 volt battery. Voltage is determined by the number of cells. Amperage is determined by the size of the cell or # of plates. You can't get double the amps out of cells that are half as big. I hate to say this, but 4 of you telling a lie does not make it the truth. If what you are saying were right, you would need cables twice as big to carry all that current . Instead they are smaller. In house wiring you have 10 times the volts but the fuse size is still determined by the wire size. 2 batteries of the same size will produce the same wattage. 6 volts = high amps & 12 volts at lower amps. You can't get something from nothing.

So, the 4 of us are liars?

Why? Why are we telling you lies?

What about the link I sent you?

Ohm's Law calculator. Did you look at that?

Click on it. See for yourself. Here it is again.

Quoting Removed, click Modern View to seeThe whole of your arguments are based upon 'beliefs' and numbers pulled out of 'thin air' with no supporting hard facts. You keep on with amp & small/large cells............a "belief". For some FACTS, go to Interstate battery, auto batteries, look up 1954 Chevy 6v & 1956 Ford 12v. CCA for the 6v is about 100amps less than the 12v. That is two. Knock yourself out, as they list hundreds.

Try dealing in FACTS, not beliefs, what some mechanic told you or anything except facts. I notice other inconsistencies, too, such as mixing 12v starters and 6v starters. Here in this thread we are dealing with 6v starters exclusively, albeit, some using 12v batteries and some using 6v batteries. Try to keep your comparisons relevant.

You are comparing a group 1 6 volt to a group 24F 12 volt, a much larger battery. CCA can vary that much just in the quality of the battery.
