120VAC (RMS) has a peak voltage about 170VAC.
No matter how it's rectified, you still have 170VDC peak. Even if it's pulsed, your batteries won't like that.
If you run the 120VAC through a suitable step down transformer, then rectify it, that'll work, but it'll probably cost you near the same as a "proper" battery charger anyway.
