Overall, the energy stored in batteries is in the form of chemical potential energy, which is converted into electrical energy when the battery is used to power a device. Not all batteries are the same. There are many types of batteries, each with its own way of storing and releasing energy.
There is energy stored in the battery in the form of chemical potential energy. Yes, it is true that a current can be described as moving electrical charges. However, it is not true that these charges are "stored in the battery". Let me give a simple analogy. If electric current is like water, then a battery is like a water pump.
Batteries store energy through chemical reactions that occur between the materials inside them. During charging, energy is converted into chemical potential energy, which is then released as electrical energy when the battery is used. How do different battery chemistries store energy?
There are no batteries that actually store electrical energy; all batteries store energy in some other form. Even within this restrictive definition, there are many possible chemical combinations that can store electrical energy--a list too long to go into in this short explanation.
A battery for the purposes of this explanation will be a device that can store energy in a chemical form and convert that stored chemical energy into electrical energy when needed. These are the most common batteries, the ones with the familiar cylindrical shape.
The area is the energy, E = 0.5 * Q * U, Q = U * C Total Energy stored in the capacitor, = QV/2 = 0.5 CV^2 where, Q = amount of charge stored when the whole battery voltage appears across the capacitor. V= voltage on the capacitor proportional to the charge. Then, energy stored in the battery = QV
