There are typically two cables, one is usually red and the other black.

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 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.


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.
