FAQs about Capacitors act like batteries
Is a battery a capacitor?
Since the energy stored in the capacitor is proportional to the square of the voltage, once the voltage drops off significantly, the current will increase in inverse proportion and so the remaining energy will be extracted quite quickly. Bear in mind that batteries typically have much higher capacity than capacitors. The simple answer is no.
Can a capacitor replace a battery?
It is common knowledge that capacitors store electrical energy. One could infer that this energy could be extracted and used in much the same way as a battery.

Can a battery store more energy than a capacitor?
Today, designers may choose ceramics or plastics as their nonconductors. A battery can store thousands of times more energy than a capacitor having the same volume. Batteries also can supply that energy in a steady, dependable stream. But sometimes they can't provide energy as quickly as it is needed. Take, for example, the flashbulb in a camera.
Can You charge a capacitor with a battery?
However, for devices that need consistent, long-term energy supply, a battery is still the best option. You can easily charge a capacitor using a battery. The charging process is quick, and this is commonly done in circuits where capacitors are used to smooth out power supplies or manage energy flow.
