Primary batteries readily available to consumers range from tiny button cells used for electric watches, to the No. 6 cell used for signal circuits or other long duration applications. Secondary cells are made in very large sizes; very large batteries can power a submarine or stabilize an electrical grid and help level out peak loads.
Batteries come in many shapes and sizes, from miniature cells used to power hearing aids and wristwatches to, at the largest extreme, huge battery banks the size of rooms that provide standby or emergency power for telephone exchanges and computer data centers.
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.
Storage batteries can preserve the electricity generated when intermittent power sources are available. This power can be later used in blackouts or, as part of load balancing, in times of peak demand. Storage batteries can also provide renewable power in a stable form, eliminating any disturbances that intermittency might cause.
Batteries are a non-renewable form of energy but when rechargeable batteries store energy from renewable energy sources they can help reduce our use of fossil fuels and cut down carbon dioxide and greenhouse gas production. Find out why batteries may have a key role to play in making our energy supply greener.
The single-use batteries, sometimes referred to as primary types, are commonly batteries, and these are readily available in supermarkets and shops. Batteries supply Incorrect disposal of both rechargeable and single use batteries can lead to chemicals leaking into the environment eg water and soil.

An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons. When a battery is connected to an external electric load, those neg…
