How they know that cable of battery is positive and the other one is negative?

I assume you're asking how can you tell which is positive and which is negative? The red cable is positive in the black cable is negative. But if they are not color-coded the positive battery post is slightly larger than the negative battery post. If you try to connect the negative cable to the positive post it would be a tight fit and if you connect the positive cable to the negative post it would be loose.

Connect the other jumper cable negative clamp (Black color) to the negative post of a good battery. 5. Start your Mercedes. 6. Reverse the 1-4 steps when the car starts successfully.

How do you connect a car battery cable to a battery not in the car?
It would be essentially the same as connecting a battery in the car, except with longer cables. You would have to use jumper cables to extend the car battery cables. Be sure to follow ALL safety procedures. Do NOT let anyone or anything metal touch anything else except where you make the connections. Do not touch the metal connectors themselves. I assume there is no battery in the car. I will call the battery that is not in the car the "external battery". First connect the positive ("+", usually red) jumper cable to the positive car battery cable, & then the other end of that jumper cable to the positive external battery terminal. Then do the same with the negative ("-", usually black) car battery cable & jumper cable. The last thing you connect should be the far end of the negative jumper cable to the negative terminal of the external battery. When you are ready to disconnect the external battery from these cables, do so in reverse order, starting with disconnecting the negative ("-", usually black) jumper cable from the negative external battery terminal.

How do i identify negative and positive battery cables on a 1991 ford mustang. there are no red or black markings?
The Negative - Battery Cable will be connected to ground. Ground is the engine block, frame, or other non-electrical part of the vehicle. The other cable is positive. Another way is to connect an ohm meter black test probe to the engine block and touch the red test probe to the cable you think is ground -. If the circuit is complete you have found the negative cable.
Do you hook up the positive or negative wire first on a battery?
Always hook up the red or positive cable first, otherwise you could cause a short between the battery and the car through your wrench. Ths of course could cause an explosion or other problems. The black or negative cable goes straight to the engine and the car's frame, so your wrench can touch the frame when you are tightening the cable end on the battery with no worry.
Is positive on a car battery Red or black?
The red jumper cable attaches to the positive end of the battery. Make sure both cars are turned off before attempting to connect the cables and do not touch the metal portions of the cables together or to any part of the car except for the proper battery terminal.You'll first attach the positive (red) cable to the positive terminal of the dead battery. Then attach the other end of the red cable to the positive terminal of the working battery.Then attach the black cable to the negative terminal of the good battery, and finally attach the other end of the black cable to the negative terminal on the dead battery.Make sure everyone is clear of the engine and moving parts before starting the engine of the good car. Allow it to run for a couple of minutes, revving the engine slightly. Then start the engine of the dead car.Be sure to remove the cables in the reverse order of the way you put them on - negative first, then positive.
