Can a Capacitor act as a Battery? The capacitor can not act as a battery because capacitors discharge quickly whereas batteries discharge slowly. In this article, we will understand why can''t a capacitor act as a battery. Capacitor and Battery are considered electronic devices that store potential energy and releases it when required.
It depends on the expected lifetime you need. If you are going to have more than tens of thousands of power fail events, then capacitors would assure you of a longer life, useful if it was an unattended situation like a remote island. However a battery would be so much smaller, cheaper and easier to use, that's the way I would go.
However, I saw some videos and people usually do connect batteries directly with capacitors. Also, the current that flows from the battery to the capacitor is somehow of low magnitude, since it takes some considerable time to make the capacitor have the same voltage as the battery. I would like to know why this happens, thanks.
The first, a battery, stores energy in chemicals. Capacitors are a less common (and probably less familiar) alternative. They store energy in an electric field. In either case, the stored energy creates an electric potential. (One common name for that potential is voltage.)
This will happen because there is no resistance between the capacitor and the battery, so the variation of current by time will be infinite. Obviously, this is true when talking about ideal components and non-realistic circuits. I thought that doing it in real life would cause sparks, damaged components, explosions, or whatever.
As others have said, the fact that the amount of energy being stored in a capacitor is a factor of the voltage squared makes having a bank of capacitors charged up to a high voltage seem appealing, though depending on the voltage level can be difficult to design around.
Capacitors have a pretty basic design. The simplest ones are made from two components that can conduct electricity, which we’ll call the conductors. A gap that doesn’t conduct electricity usually separates these conductors. When connected to a live circuit, electrons flow in and out of the capacitor.

To connect electrolytic capacitors to a battery safely, one must take several important precautions. Check Polarity: Ensure the capacitor is connected with the correct polarity. Voltage Rating: Use capacitors with voltage ratings higher than the battery voltage. Capacitance Value: Select appropriate capacitance values for the intended application.
From this definition, you might assume that a capacitor is a type of rechargeable battery, storing charge to use later. However, a capacitor''s characteristically low charge capacity compared to conventional battery cells generally makes them ill-suited to prolonged use as a power source. The other characteristic that makes them disadvantageous for prolonged power …

Capacitors are a circuitry tool, and supercapacitors use them in a battery-like design. Batteries move energy using chemical reactions, and these can deteriorate over time.
The simplest solution is to use a small 4.8V NiMh battery pack (just Google for examples). These are very common for hobby use to run the receiver and servos in radio-control gliders.

A single Maxwell (for instance) BCAP0350 2.7v ultra capacitor that''s about the size of a D cell has a capacity of 1300 Joules (1.3 x 10^3 J). It is extremely useful to use ultracaps to charge batteries if the nature of the power source is intermittent and high current (say, at 35 to 175 Amps, also within spec of the one I listed).

According to this answer, you''d want to use capacitors rated for 400-450V, since per unit volume they give you most energy stored. You''ll want to charge them up to 95% of the rated operating voltage, and discharge them down to 50-100V. The lower discharge voltage depends on how good a switching converter you can put together to efficiently ...
