Rechargable Batteries

Rechargeable batteries. A rechargeable battery can also be known as a storage battery, and is technically a group of two or more secondary cells, for instance a laptop computer which may have up to six individual cells. They are however often called a single cell, such as a NiMH AA battery. When the power in these rechargeable batteries is depleted, they can be restored to a full electrical charge, by the use of a battery charger, which is used to apply electrical energy to the depleted cell. Rechargeable batteries are available in many different shapes and sizes, and be manufactured using various chemicals. Commonly used chemicals are nickel metal hydride NiMH, nickel cadmium NiCD, lithium ion Li-ion and lithium ion polymer Li-on polymer. Rechargeable batteries have many applications including uses in portable consumer devices, motor car starters, power tools and light vehicles such as wheelchairs etc.
