    But capacitors aren’t batteries. Batteries store chemical energy. Capacitors store electrical potential energy. Electronically they behave much differently.

      Yes they do… including not holding a charge when the differential drops too far.

      The real wins are in battery-backed capacitors. Charge the caps fast, then let them keep the batteries topped up.

        That’s what I do being off-grid. I have my battery bank then a series of Supercaps to essentially act as an on/off ramp//drawbridge and temper quick demands. Kinda like an inverse soft starter so this is suuuuper interesting to me.

      Only for certain types of capacitors. In practice they can overlap quite a bit, especially with common aluminium electrolytic capacitors (these form & dissolve complex aluminium oxide & hydroxide layers on the plates).
