The Rise in Voltage

Historically, the most mentions for National Battery Day online reached an all-time high on 18th February 2021 with a staggering 2287 mentions. Who knew the humble battery could steal the limelight (or LED spotlight, if you prefer)?

The Power Packed Celebration

The day is usually spent recognising and appreciating the essential role batteries play in our daily lives. From powering our gadgets, to emergency systems, to electric vehicles, today’s batteries are stepping up their game powerfully.

Batteries Unplugged

Dare consider this day as a chance to unplug and take a digital detox? After all, just like a good battery, we also need recharging now and then, don't we?


So, whether you’re a fan of the Duracell Bunny, Energizer Bunny, or just simply someone who can't live without their battery-powered devices, National Battery Day is your opportunity to celebrate these small but mightily important inventions.

History behind the term 'Battery'


The First Discovery

The term 'battery' was first used in 1749 by Benjamin Franklin to describe an array of charged glass plates. Franklin noticed that when he discharged these plates into metal objects, they produced a powerful shock. This discovery led to the development of the Leyden jar, an early form of capacitor that stored electrical energy.


The Voltaic Pile

In 1800, Alessandro Volta invented the Voltaic pile, which comprised alternating layers of zinc and copper discs separated by cloth soaked in saltwater. When connected, this early form of battery produced a stable and continuous flow of electricity. This significant advancement laid the foundation for the modern understanding of electrical energy and marked the birth of practical battery technology.


The Lead-Acid Battery

The lead-acid battery, invented by French physicist Gaston Planté in 1859, was the first rechargeable battery. This technology revolutionized early electrical systems by providing a reliable and convenient source of portable power. Lead-acid batteries were widely used in various applications, including powering automobiles, early electric vehicles, and supporting telecommunications infrastructure.


The Alkaline Battery

In 1901, Thomas Edison patented the alkaline storage battery, a significant breakthrough in battery technology. This type of battery utilized nickel hydroxide and iron electrodes, offering higher energy density and longer operational life compared to previous designs. Alkaline batteries became popular for numerous consumer devices, such as flashlights, radios, and portable electronics, and remain a staple in household power needs today.


The Transistor and Miniaturization

With the invention of the transistor by Bell Labs in 1947, a paradigm shift occurred in battery technology. Transistors enabled the development of compact and portable electronic devices, ranging from early pocket radios to modern smartphones and laptops. The demand for smaller and more efficient batteries rose, leading to advancements in battery chemistry and the introduction of rechargeable lithium-ion batteries.


Lithium-Ion Batteries

The development of lithium-ion batteries, commercialized by Sony in 1991, revolutionized portable electronic devices. Lithium-ion batteries offer high energy density, lightweight construction, and efficient recharging capabilities, making them ideal for modern gadgets. They power everything from smartphones and laptops to electric vehicles, providing longer battery life and enabling the technological advancements of the 21st century.
