Fly back transformer?

Ok, i have this transformer that i pulled out of a mac computer a couple years ago, i dont have it with me nut i think its a flyback. If it is, could i just hook it up to a battery and capacitor to make a charger or do i have to build some sort of modulator or switcher?
Almost anything helps, thanks.

You need a driver circuit see this site.
You will need a driver circuit to drive the primary windings to produce a HV output on the secondary.

There are many flyback driver circuits on this site and elsewhere, but I can't vouch for any of them.
