Plate capacitor connected to a battery (what does a battery do)
Initially (before the battery is connected) it is assumed the capacitor is uncharged, that is, there is zero charge on each plate. The battery, when connected, moves some charge from one plate to the other. Since charge cannot be created or destroyed, the deficiency of charge on one plate is equal to the excess charge on the other.

I came across a nice conceptual question on how will things change like potential, capacitance and stored energy if a capacitor is charged by a battery connected in between plates of a capacitor? Can you relate the changes when battery connected across and in between capacitor lead? electric-circuits; potential-energy; voltage;
Capacitors and batteries
With the power supply connected to the capacitor, a constant difference in potential is maintained between the two plates. This results in a certain amount of charge moving on to the plates from the power supply, and there is a particular electric field between the plates. When the battery is connected to a circuit, electrons produced by
8.5: Capacitor with a Dielectric
Once the battery becomes disconnected, there is no path for a charge to flow to the battery from the capacitor plates. Hence, the insertion of the dielectric has no effect on the charge on the plate, which remains at a value of (Q_0).
If we charge a capacitor can we discharge it into a battery?
Even if you could charge it this much, it would be pretty bad to connect it to a 1.5-volt battery. To summarize, the charging is only good if the voltage is close to 1.5 volts but capacitors have vastly variable voltage that depends on the stored energy and/or charge dramatically. All you need to charge a battery from a capacitor is to have

$begingroup$ If we insist on using a lumped element model to describe the situation then we must include at least two capacitors, one connected to each end of the battery and then connected to eachother. However, the case you describe is a little bit degenerate because you consider just a plate connected to one end of the battery and another

6 FAQs about [Battery connected to capacitor]
What happens when a capacitor is connected to a battery?
When a capacitor is linked to a battery, it conducts for a short time before becoming an open circuit. When a potential V battery is connected to an uncharged capacitor C , a transient current occurs as the capacitor plates charge. When the charge Q on the positive plate reaches the value Q = C × V , the current flow from the battery stops.
How much current does a capacitor draw from a battery?
In steady state (after a long time) an ideal capacitor does not draw significant current from a battery. A real capacitor will draw some small leakage current. The amount of leakage current will depend on the type of the capacitor, electrolytics will have higher leakage than films and ceramics.
What happens if an uncharged capacitor is connected directly to a battery?
In my understanding, theoretically, when an uncharged capacitor is connected directly to a battery of, let's say, 9 volts, instantly the capacitor will be charged and its voltage will also become 9V. This will happen because there is no resistance between the capacitor and the battery, so the variation of current by time will be infinite.
How does a capacitor charge a battery?
Hint: The charging process begins when the capacitor is linked to a battery.The charge travels from one capacitor plate to the other, creating an electric field in the gap between the two plates. The boundary conditions can be used to address this problem.
What is the difference between a battery and a supercapacitor?
Supercapacitor is supposed to be in between a Capacitor and battery. These types of capacitors charge much faster than a battery and charge more than an electrolytic capacitor per volume unit. That is why a supercapacitor is considered between a battery and an electrolytic capacitor.
Can a battery and a capacitor have the same voltage?
When you measure the voltage across the battery and the voltage across the capacitor, you'll find that they're both the same. It makes no difference whether you connect objects with equal voltage or not. There will be no current flow because the voltages are equal.
