Uh, the battery is nothing more thann a large capacitor. Capacitors are
the main components of voltage "smoothing." You know, like radio noise
suppression etc.

Actually, they're not. Capacitors /store/ electrical energy. Batteries
/create/ it via a chemical reaction. Charging a battery is not storing energy;
it's (to oversimplify) merely reversing the checmical reaction.

Technically yes, but both smooth voltage..

Batteries do, to a degree. That's not what they're designed for though.
