Question about motorcycle CDI ignitions, battery, and kickstarter?

I have a 1979 Honda cb250t that I got a couple of days ago and long story short, there's no spark. It has a kick-starter AND electric start, but it doesn't have a battery in it but it has the + and - terminal leads and what not, I was just wondering, in my motorcycle with a TIA01-20 CDI ignition, is a 12v battery mandatory for spark? Sorry if this is a dumb question, I'm no electrical genius haha!
