Battery
A battery is a portable device that stores and provides electrical energy through chemical reactions, powering everything from smartphones to electric cars and making modern life mobile. Beyond tech, it can also mean a group of similar items working together, like artillery in military contexts, or even a legal term for unlawful physical contact—highlighting how the word has evolved to pack a punch in various fields.

The world's first electric battery, invented by Alessandro Volta in 1800, was essentially a stack of zinc and copper disks separated by cloth soaked in brine, producing about 30 volts and sparking the dawn of electrochemistry—fun fact, it was so revolutionary that it led to the discovery of electromagnetism by Hans Christian Ørsted in 1820.
