Now you know why the *How to detect a short* test uses the negative terminal

Unless I'm reading all of this information correctly;

Some are saying that the discharge current flows out of the negative side of the battery; and some are saying the that the discharge current flows out of the positive side of the battery.

Interesting.

Chemists and Physicists had to get it right to make all the reactions and observations work. Current (electrons) flows from negative to positive.

Those little electron dudes don't really flow all the way through the circuit - they move sorta kinda like pool ***** all lined up and touching, and then getting bumped on one end of the line. That is to say, individual particles don't traverse the entire circuit at the speed of light (nearly) - rather, as one moves (toward whichever pole ends up being the correct pole of choice), it is replaced by another, and it is this movement that's referred to as current.

By the way, "current" is the flow of electrons, so the expression "current flow" is redundant, in much the same way as "hot water heater".

Current flows from negative to positive. But, you couldn't tell that from a DC electrical schematic! Could it be that our battery posts are marked opposite of what their true properties are? Just to reflect conventional theory?

It's O.K. though, as long as you keep your symbols (+ or -) straight, the circuit will still work!

again, who is going to provide proof? Unless you can prove it, it is just theory. I say it goes from neg to pos, but cannot prove it. Like Neb86 said, as long as you are consistent with the connections, who cares? It's just a way to keep the correct polarities together.

The battery markings are correct.

As far as proof- Take a course in Chemistry and prove it to yourself.

point is, it can't be proven. just a theory.

No, take a course in Chemistry, it really is simple to prove.

It can, and it has - probably before you were born. Just because a person can't go out in the garage and hook up a battery and watch the electrons with a video camera, doesn't mean that "black magic" electrical stuff cannot be proven.
