I too am a clueless female, but I always carry in the back of my car a Clark Jumpstart Unit with Tyre Compressor unit as bought from
Argos for about £40, although you can get them cheaper if you shop about (also keep a bottle of rad weld, tyre weld just in case radiator or a tyre goes) Anyway I digress...in event of a flat battery, a simple case of red to positive on the battery & black to the top of the strut. (Even I can do that) - 20 secs later, car starts! & then it is a case of periodially plugging the jumpstart unit into the mains at home to re-charge. Woolworths used to do an even simpler one, that plugs into the cigarette lighter for about a £10 under their workshop brand.
Hope you got sorted. I know the awfull feeling when the car won't start and you have million & other things to do.
