Batteries are a form of stored energy. They contain chemical energy that can be converted into electrical energy when needed.

The chemical energy needed for reactants to form products is called activation energy. This energy is required to initiate a chemical reaction by breaking bonds in the reactants.

The energy can come from just about any source of AVAILABLE energy.
The energy needed to form a wave in a pool comes from a combination of factors such as wind, gravity, or a mechanical force. This energy is transformed into the kinetic energy of the water particles, causing them to oscillate and propagate as a wave.
thermal energy is needed to do that job. as opposed to mechanical potential or chemical energies.
Activation energy is the minimum amount of energy required for a chemical reaction to occur. It acts as a barrier that reactants must overcome to form products. This energy is needed to break bonds in the reactant molecules before new bonds can form in the products.
The energy needed to remove an electron from a negative ion to form a neutral atom or molecule is called the electron affinity. It represents the energy change when an electron is added to a neutral atom or molecule to form a negative ion. The higher the electron affinity, the greater the energy needed to remove an electron.
