You do not recharge your car battery with another car, when you connect the batteries together to get your car started, it is called jumping it, and only partially gets the battery working again. It should not be attempted if you do not know what you are doing because it can be dangerous.
you need someone to jump start it
you can go to Canadian tire and buy a recharge kit for the a/c it is really easy to do and i think they cost about 35 bucks
generally it only takes a few minutes to recharge your battery, depending on how dead it is.
