The main difference between a battery and a capacitor is that Battery stores charge in the form of chemical energy and convert to the electrical energy whereas, capacitor stores charge in the form of electrostatic field.
Customer ServiceThe battery will supply current to the capacitor until the capacitor''s voltage equals the battery voltage. During this charging process, the voltage difference between the battery and the partially-charged capacitor is the voltage drop of the resistor R, resulting in heat dissipation = energy loss.
Customer ServiceThe key distinction between a battery and a capacitor lies in how they store electrical energy. While a battery stores energy in chemical form, converting it back into electrical energy as needed, a capacitor stores energy in an electric field.

Customer ServiceThe main difference between capacitors and batteries is their capacity, charge/discharge rate, size/weight, and polarity. Batteries have higher watt-hour ratings and longer charge/discharge rates, while capacitors are more compact and have quicker charge/discharge rates.

Customer ServiceA 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.
Customer ServiceBattery vs capacitor: these two energy storage devices are often compared due to their similar functions, but they operate in fundamentally different ways. A battery is a device that converts chemical energy into electrical energy. It consists of one or more electrochemical cells, which contain two electrodes immersed in an electrolyte. The chemical reactions inside
Customer ServiceWhen battery terminals are connected to an initially uncharged capacitor, the battery potential moves a small amount of charge of magnitude Q Q from the positive plate to the negative plate. The capacitor remains neutral overall, but with charges +Q + Q and −Q − Q residing on opposite plates.
Customer ServiceCapacitors function a lot like rechargeable batteries. The main difference between a capacitor and a battery lies in the technique they employ to store energy. Unlike batteries, the capacitor''s ability to store energy doesn''t come from chemical reactions but from the physical design that allows it to hold negative and positive charges apart.
Customer ServiceFrom 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
Customer ServiceCharge equalization of series connected energy storage elements (batteries and super-capacitors) has significant ramifications on their life and also reduces their operational hazards.

Customer ServiceThe flow of electrons onto the plates is known as the capacitors Charging Current which continues to flow until the voltage across both plates (and hence the capacitor) is equal to the applied voltage Vc. At this point the capacitor is said to be "fully charged" with electrons.
Customer ServiceBatteries have a higher energy density, meaning they can store more energy for extended periods, whereas capacitors have a lower energy density, ideal for applications requiring rapid bursts. Capacitors generally have a much higher cycle life than batteries, as they can withstand repeated charging and discharging without significant degradation.

Customer ServiceA battery and a capacitor are hardly equivalent. A battery has a voltage that's a function of the chemistries of the materials inside it. This voltage is constant. As the stored energy in the battery is exhausted, the voltage decreases some.
When a capacitor is connected to a battery, the charge is developed on each side of the capacitor. Also, there will be a flow of current in the circuit for some time, and then it decreases to zero. Where is energy stored in the capacitor? The energy is stored in the space that is available in the capacitor plates.
This logically suggests that when you talk about an "equivalent capacitance" to a battery that you mean a capacitor that stores or can deliver the same energy as the example battery. In theoretical terms your calculation is correct for an idealised battery (constant voltage throughout discharge, defined mAh capacity) and an idealised capacitor.
If you need a lot of energy storage and the ability to quickly charge and discharge, then a battery is probably the best choice. However, if you need more efficiency or stability in terms of current flow, then a capacitor is the better option.
Using binary weighted resistor values a load able to accept a wide range of voltages, at APPROXIMATELY constant power, can be constructed. As can be seen, a battery holds an immense amount of energy for its size and cost, compared even to the most energy dense "super" capacitors. Notes:
The capacity of the capacitor to hold electric charges is termed capacitance. Capacitors store energy by holding the pairs of opposite charges. While the basic capacitor is like two metal plates with a gap, capacitors nowadays come in many shapes, sizes, and materials. Capacitance is defined by the given formula : C = Q/V Where,
