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.
|
|
Batteries come in a variety of sizes and shapes. The most common are AAA, AA, C, and D sized.
|
|
Batteries can be made with lead-acid, LiPo, Li-ion, NiMH, alkaline, and NiCd.
|
|
NiMH batteries are nickel metal hydride and are commonly used in portable electronics such as toys and portable home phones.
|
|
Alkaline batteries are used in portable devices such as flashlights, toys, portable home phones, and calculators. These come in 1.5 and 9 volts.
|
|
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.
|
|
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.
|
|
Rechargeable batteries will eventually degrade to the point that they are no longer usable.
|
|
Batteries can come as wet cell, or dry cell.

|
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.
|
|
Lemons can also be used to make power.
|
|
The smallest battery in the world was created with a 3D printer, and is only the size of a grain of sand.

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.
