It is optimal for your lithium-ion smartphone battery to top it off and keep its charge between 40-80%, rather than let it drain 0% and charge it all the way up.

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.

Li-ion are lithium ion batteries and are not toxic and are smaller and charge faster than NiCd batteries. They are commonly used in tablets, gaming systems, and cell phones.

Li-Po are lithium polymer batteries and are light weight and have high current output. They are commonly used for remote control vehicles.

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.

Petroleum companies bought rights to battery patents and sued anyone who used them (with gag orders

Rechargeable batteries will eventually degrade to the point that they are no longer usable.

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).

The Germans invented an infrared scope during WWII. A 13-kilogram battery pack was worn on the back, and the scope could be used for 15 minutes at a time. It was codenamed Vampir

Batteries can come as wet cell, or dry cell.

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.)

Manhattan's southern shore is referred to as 'The Battery'.

It is possible to use potatoes as a source of battery power, although they are not capable of producing a lot of it.

It is possible to make a battery that will last centuries using nuclear waste and artificial diamonds.

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.

Lemons can also be used to make power.

A lead-acid cell capable of producing a very large amount of current, the forerunner of today's automobile battery, was devised in 1859 by Frenchman Gaston Planté.

If all new cars produced were powered by lithium batteries, the world would run out of lithium in ~30 years.

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

The smallest battery in the world was created with a 3D printer, and is only the size of a grain of sand.

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.

The 9-volt battery was introduced for improved portable transistorized radios that had lower voltage requirements than the originals.

Prior to the Energizer Bunny becoming famous as the face of Energizer batteries, a pink bunny was used by Duracell. Duracell forgot to renew their trademark and Energizer scooped it up.

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

The iconic Nokia 3310s battery capacity is 3 – 4 times less than an average smartphone today.
