Transformer replacement

Do most transformers used with ac current transform to ac or can it go to either ac/dc?
And what about the basic universal ones -240 to 24 , - ,are they ac in the 24v still or dc
I'm replacing one in a old a charger that is 120 that converts to 12v dc but hoping I can go 1 leg on the 240/24 I already have laying around if the amps an all match up .

thanks

Yes all transformers are AC to AC.

I doubt a 12 volt charger use a 12 volt AC output transformer

Rather mixing up several items in the question.
Here is a pix to show at least the major components, in a simple AC powered charger. A brute force charger may even eliminate the capacitor and the regulator.

No..... you can't use that old 24v HVAC leftover transformer for a charger.
Even if you could...... it's only good for less than 2A.

I had a spair new one an was just curious-
even though theres 2 rectifiers, to convert to dc . I guess it's not big enough for the 10 Amps needed.

If you converted that transformer to DC..... you'd have roughly 33 vDC at 2A.
