Batteries are used everyday by people for many different portable devices, automobiles, boats and more. Learn some interesting facts and important history about batteries. Batteries were discovered before mechanical generators and turbines to created a steady stream of electricity. With the discovery of batteries people began to understand the importance of having a source of electricity.

Benjamin Franklin's famous experiment to attract electricity by flying a kite in a lightning storm was only one of many late eighteenth- and early nineteenth-century experiments conducted to learn about electricity. The first battery was constructed in 1800 by Italian Alessandro Volta. The so-called voltaic pile consisted of alternating discs of silver and zinc separated by leather or pasteboard that had been soaked in salt water, lye, or some alkaline solution.

Strips of metal at each end of the pile were connected to small cups filled with mercury. When Volta touched both cups of mercury with his fingers, he received an electric shock; the more discs he assembled, the greater the jolt he received.

Volta's discovery led to further experimentation. In 1813, Sir Humphrey Davy constructed a pile with 2,000 pairs of discs in the basement of the Royal Institution of London. Among other applications, Davy used the electricity he produced for electrolysis—catalyzing chemical reactions by passing a current through substances (Davy separated sodium and potassium from compounds).

Only a few years later, Michael Faraday discovered the principle of electromagnetic induction, using a magnet to induce electricity in a coiled wire. This technique is at the heart of the dynamos used to produce electricity in power plants today. (While a dynamo produces alternating current (AC) in which the flow of electricity shifts direction regularly, batteries produce direct current (DC) that flows in one direction only.)

In the United States, Thomas Edison was experimenting with electricity from both batteries and dynamos to power the light bulb, which began to spread in the United States in the early 1880s.

Batteries are a device that is made up of electromagnetic cells that are able to provide power to electrical devices. Batteries have a positive terminal called a cathode, as well as a negative terminal called an anode. Batteries can be for a single use, which are also referred to as disposable, or for multiple uses called rechargeable. Batteries can come in all shapes and sizes, from tiny batteries for small items such as hearing aids to larger batteries that are capable of powering cars, boats, and even large data centers. Batteries were invented in 1800 when Alessandro Volta built an electrochemical battery. In 1748 Benjamin Franklin was the first to use the word 'battery' in reference to Leydon jars (a power source), a word he borrowed from military terminology.

The word 'battery' in reference to the power source device is borrowed from the word 'battery' used to reference a group of weapons working together.

Batteries work by providing continuous DC (direct current) electricity. The battery will work until all of the energy has been used up. If it rechargeable it can be used again. If it is not rechargeable then it is garbage.

The power in a battery is created by chemistry.

Rechargeable batteries were invented in 1836 by an English chemist. This battery was designed with lead-acid technology and is still the type used for car batteries.

Smoke Detectors mostly chirp in the dead of night because the chemical reaction in batteries slows down when the air get’s colder thus tripping the detectors low battery detector.

Batteries come in a variety of sizes and shapes. The most common are AAA, AA, C, and D sized.

There is a battery-powered bell at Oxford University that has been continuously ringing for over 175 years. No one knows what the battery is composed of and no one wants to take the device apart in order to figure it out.

Batteries can be made with lead-acid, LiPo, Li-ion, NiMH, alkaline, and NiCd.

Once the Tesla Gigafactory is operating at 100% capacity, it will churn out more lithium-ion batteries in one year than were produced worldwide in 2013

NiMH batteries are nickel metal hydride and are commonly used in portable electronics such as toys and portable home phones.

LES1, a satellite that had been abandoned in 1967, recently started transmitting again, after its batteries decayed, shorting the solar panels straight to the electronics

Alkaline batteries are used in portable devices such as flashlights, toys, portable home phones, and calculators. These come in 1.5 and 9 volts.

Disposable electronic cigarettes contain perfectly good rechargeable lithium-ion batteries.

NiCd batteries are nickel cadmium batteries and they are capable of holding more energy. The drawback is that cadmium is toxic and hold less energy every time if not fully discharged before recharging.
