Connect two batteries to start auto

Dear good night, my query may be half silly but I don't want to exploit the battery.
I have a VW Fox for using it almost nothing and leaving the trunk open for a long time the battery can not start the car ran out but it is relatively new.
As I have it in the garage and I can't take it out alone, I thought about taking the battery out of my lady's car and connecting it to the battery of my car, the other problem is that I don't have wires with clamps. I ask can I connect a charged battery (without car) to my discharged? Can I do it with house power cables?
In the almost negative answer, I make another query, if I take out the discharged battery and connect it to a cell phone charger that has 4.5-9.5 VDC output and max. 800mA will charge something to the battery? I notice that with a little more load the car starts.
I very much appreciate your comments.
regards

To your query you can not start the car by connecting the battery with cables for domestic use, the amperage that circulates melts the cables, WHAT IF YOU CAN DO IS CONNECT THE BATTERIES WITHOUT STARTING, THE BATTERIES WILL LEVEL IN THEIR CHARGE, IT IS LIKE VESSELS COMMUNICANTS, YOU LEAVE IT FOR 4 HOURS AND YOU WOULD HAVE A MORE OR LESS COUPLE IN BOTH BATTERIES, What you can do is take out the bat.de one car and put it in the other: start your car, take out the battery, the car must be kept running and you connect yours discharged with the car a little accelerated and leave it running for about 30 minutes, the car battery should receive enough charge to work well.
Any traffic does not charge discharged battery, you need one that at least generates in continuous about 17 volts to have amperage to overcome the resistance to circulate energy through the discharged battery.

Good morning, it is essential to have a pair of extensions for batteries with their crocodiles, which is of the world cable number 8, since you have 2 cars and can suffer from low batteries for not using them, I recommend that you get those cables. It would only be enough to remove the charged battery and hook the cables directly to the discharged battery without removing terminals, in their respective polarity, then start the car and ready, carefully remove the hooks or crocodiles. The question of charging the battery with that charger indicated is not possible because the voltage is low and the amperage is very low, more amperage and voltage would be needed.

To connect the batteries, and try to start the car, you need two wires of the same thickness as the battery.
To charge the battery, it is not enough with a cell phone charger. It can be with any 12 volt transformer, no matter amperage. It is only a matter of connected time.

Hello, you can start the car too, pushing it, placing second and releasing the clutch in contact, and you would avoid all that mess. (Even if this battery has absolutely no battery at all and this charge would begin) or another way not recommended to start the car, it is with any iron of a certain thickness, from battery to battery respecting the positive and negative, you can also start the car, The precaution is that maybe somebody else is required and this same iron is going to warm up a bit (When it turns on as it passes current and tries not to touch more than the terminals!) if gloves are recommended. (Remember that the iron carries current like any metal.) Example of the iron used in chains or in construction. or some similar.

Dear, I thank you for all the information provided, I tell you to take out the battery of my lady's car with two 2.5 mm cables of household electricity connect terminal with terminal respecting polarity and starting with the positives, leave it like this 15 minutes later I gave boot and started perfect. The other battery was put back in his car and the other also started bone that did not take away much charge.
Thanks again.
regards
