Modern cars have computers and other sensitive electronics to fire the ignition coils and whatnot. Without a properly working electrical system, you can't expect these components to work. There'* electronic ignition, electric fuel pumps, electric radiator cooling fans, and so much more. You definitely need a working battery in a car these days!
And check those battery cables too. Every time I needed battery cables, they didn't get found until after putting in a new battery or alternator and having things work for a few weeks, but then I'd be out somewhere, and my car wouldn't start. Typically when the car was warm and had been running. It'* always fun to get stranded someplace far away from home isn't it? Just check your battery cables for corrosion, okay? Especially the positive cable, as that'* the one that always corrodes up on me.
