A battery is a device that stores electrical energy through a chemical reaction and converts it back into electrical energy when needed. European legislation regulating the production, distribution, use, and disposal of batteries and accumulators.

A battery converts chemical energy into electrical energy by a chemical reaction. Usually the chemicals are kept inside the battery. It is used in a circuit to power other components. A battery produces direct current (DC) electricity (electricity that flows in one direction, and does not switch back and forth).
Some are used in batteries because they react with the metals in a cell, producing electricity. Acids and alkalis can be dangerous. when the electrodes are connected a circuit is made. A chemical reaction causes electricity to from from one metal to the other and back through the electrolyte. (chemical energy is converted to electrical energy)
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.
Batteries were invented in 1800, but their complex chemical processes are still being studied. Scientists are using new tools to better understand the electrical and chemical processes in batteries to produce a new generation of highly efficient, electrical energy storage.
