At its core, a battery transforms chemical energy into electrical energy through a series of redox reactions.
Work done in electrical systems is calculated using the formula: Work Done (W) = Voltage (V) × Charge (Q). In more detail, work done in an electrical system refers to the energy transferred when an electric charge moves through a potential difference (voltage). The formula W = V × Q helps us understand this relationship.
Free QuoteNo, the work done by a battery is not always equal to the thermal energy developed in the electrical circuit. In case of a non-ideal battery, the work done by the battery is the sum of the thermal energy developed in the electric circuit and the thermal energy developed in the internal resistance of the battery.

Free QuoteWhen you turn an electrical appliance on, the potential difference of the mains supply causes charge (carried by electrons) to flow through it. When charge flows through a resistor energy is transferred to the resistor, so the resistor become hotter. The electrical work done by the battery is equal to the energy transferred to the resistor.

Batteries are used to store chemical energy. Placing a battery in a circuit allows this chemical energy to generate electricity which can power device like mobile phones, TV remotes and even cars. Generally, batteries only store small amounts of energy. More and more mobile devices like tablets, phones and laptops use rechargeable batteries.
The battery performs a chemical reaction that releases energy. The energy is released in the form of electricity, and the reaction can occur when the battery is connected to the circuit. Why do batteries go flat?
“The ions transport current through the electrolyte while the electrons flow in the external circuit, and that's what generates an electric current.” If the battery is disposable, it will produce electricity until it runs out of reactants (same chemical potential on both electrodes).
Rechargeable batteries (like the kind in your cellphone or in your car) are designed so that electrical energy from an outside source (the charger that you plug into the wall or the dynamo in your car) can be applied to the chemical system, and reverse its operation, restoring the battery's charge.
