Mechanical energy
A battery converts chemical energy stored in its cells into electrical energy. When a circuit is connected to the battery, chemical reactions occur within the battery that release electrons, generating an electric current.
In most cases, chemical energy stored in the battery produces the electric current. Rechargeable batteries are capable of taking electric currents and using them to reverse the chemical reactions, thus gaining more chemical energy that can be used readily.
An electric clock typically uses electrical energy, which is converted into mechanical energy to power the movement of the clock hands. The electrical energy is provided by a power source such as a battery or a wall outlet.
DC (Direct Current) electricity is the only kind which can be stored. For this reason, it is what you get from all batteries. Flashlight batteries usually output that electricity at 1.5 volts when they are new.

A battery stores chemical energy and converts it into electrical energy when connected to a circuit.
The energy stored in a car battery, or other cells or batteries, is chemical energy.
The type of energy a battery supplies is either electrical of chemical.
The popular energy of flashlight are Rechargeable Li-on battery, Alkaline battery.

An electric fan converts electrical energy into kinetic energy to produce air movement.
