Do the following in this order: clip the positive end of some jumper cables to the positive terminal of the good car battery (positive is usually red). Then, clip the positive end of the jumper cables to the positive end of the bad car battery. Now connect the negative end of jumper cables to the negative terminal of the good car battery and then connect the other negative end to THE BLOCK of the car with the dead battery. Do not attach it to the battery! Any metal place on the engine mount itself will do. To take it off, do everything in reverse order.
The above answer can be done, but is not recommended. The recommended practice is to remove the battery and put it on a trickle charger. You can damage the alternator by blowing the diodes on the car with the good battery if you do what's stated above. Another thing is, you have to watch the age of the battery you are trying to charge; anything older than a year requires a battery fluid check, if possible. If the fluid is at a good level, put it on the charger. If it is low or dry, fill it with distilled water, wait for about and hour then put it on charger. I've linked a good point of reference below from a top automotive battery manufacturer.

Some car battery charges will not charge a completely dead battery. You need to find a type of battery charger that is designed to charge a completely dead battery. You can get around this by hooking a car with a working battery up to the dead battery with jumper cables. The alternator/charging system of the car with the good battery will charge the dead battery. Leave them connected for about 30 min, then disconnect and try to use the battery charger again. If it still won't charge, hook it up to the car with the good battery for a longer period of time.
