The question is more about battery chemistry than physics, but here are some things to keep in mind: Capacitors can typically retain MUCH less charge than a battery, since the latter stores energy in chemical form Supercapacitors are a class of capacitor that can be used for precisely the purpose you describe. From the Wiki page: Supercapacitors are ...

What does this mean? It means that your model isn't valid. Only in the context of ideal circuit theory does a voltage source produce a voltage across independent of the current through. In this context, connecting two (ideal) voltage sources in parallel leads to a contraction, e.g., $$1 = 2$$ But physical voltage sources cannot produce unlimited ...

Easyest anser is a battery with more volt than the other will drain until they are equle voltage unless you put a diode from low battery + to full battery +. Sorry for spelling errors

How quickly discharge will occur in the situation you sketch depends entirely on the surface properties of the negative electrode. For current to flow, electrons need to be released from the negative electrode; once they are free, they will accelerate unimpeded to the positive electrode. They will arrive there with 1.5 eV of energy, causing a small amount of ...

Electrons (and other charge carriers, e.g., ions) in vacuum travel without resistance. However, as pointed out, correctly, in the other answers, there are no charge carriers in vacuum. Nevertheless, electrons can escape from the terminals if they have a kinetic energy which is bigger than the potential barrier of the terminal surface, i.e., the work ...

Lines of electrostatic force exist between the positive and negative poles of the battery, even though they're separated by a vacuum. Vacuum permittivity is ε0 = 8.854 * 10^-12 farads per meter. By convention, this is called the dielectric constant of 1, a baseline against which the dielectric permittivities of other materials are compared. ...

In vacuum there are no charge carriers like ions or electrons. With nothing to carry charge, i.e. current, such a battery would discharge much, much slower than when the battery poles are connected by something that can carry charge like a conductor or an imperfect insulator.
