An electric battery makes it possible to accumulate energy through electrochemical processes.
Battery is a term that has various uses and meanings that are very different from each other. The electric battery , for example, is a device that accumulates energy through electrochemical processes. This type of batteries, also known as accumulators , work as secondary electricity generators since their operation depends on a previous electrical charge.
Among the wide range of batteries of this type we can especially highlight, due to the frequent use we give it in our daily lives, the alkaline battery . This is used in various gadgets and devices such as a watch, an alarm clock, a calculator or even hearing aids.
Non-rechargeable and rechargeable batteries
A non-rechargeable battery or primary cell is known as one whose transformation of chemical energy into electrical energy is not reversible. This means that, once the available reagents are exhausted, it is not easy to return energy to the cell by electrical means.
A rechargeable battery or secondary cell , on the other hand, allows the reversal of its internal chemical reactions through the contribution of electrical energy. This way its original composition can be restored.
The alkaline battery used in flashlights is an example of a primary cell. Among the secondary cells, we can mention the lithium ion battery in telephones, the lead-acid battery in automobiles, and the nickel-zinc battery in cameras.
There are several issues that are analyzed when choosing between one or another battery. Battery life is one of them, as is battery capacity . In the case of rechargeable batteries, you need to have a charger that supplies the current necessary for recharging. This may be a portable charger, although a charging cable may also be used to connect the device to an outlet . The important thing is to always pay attention to the low battery indicator to know when recharging is necessary.
recycling
It is necessary to know that there is a useful life of the battery . When non-rechargeable batteries run out of reagents, they are no longer suitable for normal use. The same with rechargeable batteries if they no longer maintain the charging capacity.
The death of the battery is an economic inconvenience for those who have to buy a new one, but above all it is an ecological problem. Battery toxicity is usually high due to its heavy metal content. That is why it cannot be disposed of anywhere: it is necessary to have it reach a battery recycling center for recovery or correct final disposal.
The energy storage offered by a car battery is essential for the operation of the vehicle.
The drums as a percussion instrument
In music , the drums are a percussion instrument that is born from the union of other instruments . The drums and timpani originating from Africa and China , the cymbals from Turkey and the European bass drum come together to form the drums, which today are used in various genres such as rock, pop and jazz.
Drummers is the name given to those musicians who dedicate themselves to playing the aforementioned instrument. Among the best of this art throughout history is, for example, the Danish Lars Ulrich of Metallica, who is characterized because his gift allows him to play both simple rhythms and very fast and complicated compositions.
Along with him, we should not miss the opportunity to name other great international drummers such as John Bonham from Led Zeppelin , Nicko McBrain from Iron Maiden , Dave Grohl from Nirvana , Ringo Starr from The Beatles , Keith Moon from The Who or Roger Taylor from Queen .
A drum kit is a percussion instrument.
The concept in the military field
For the military field ( artillery ), the battery is a group of pieces that, thanks to their arrangement, can operate together.
Its formation varies depending on whether it is coastal artillery (4 small pieces or 2/3 large-caliber components), field artillery (which has 4 or 6 elements) or anti-aircraft artillery (4 or 8 pieces).
Kitchenware
In cooking and gastronomy , the battery is the equipment that consists of several elements that allow the cook or chef to prepare various types of food .
More precisely, the utensils that are part of this type of cookware are pots, saucepans and pans of various sizes. However, they also usually come with other elements such as graters, drainers, cooking plates and even lunch boxes. It should also be noted that all of them usually come in two types of materials: vitrified steel or stainless steel.
The notion in psychology
Finally, we can mention that the concept of battery is also used in psychology . In this case, the battery refers to a series of psychometric instruments that are used to carry out a comprehensive evaluation of how a certain mental procedure works.
These processes can be emotional, cognitive, personality or other types. Typically, the application of the psychometric battery takes place within the framework of neuropsychological tests.
