cell phone batteryWe’ve been discussing the first batteries which were developed and in use in the early and middle 19th century. Today, the beginning of the 21st century, we use batteries for an enormous number of products and conveniences, and the vast majority of those batteries are rechargeable.

Cell phones, laptops, MP3 players, digital cameras, portable power tool all require batteries, and rechargeable ones are the most convenient and cost effective.

The concept of a rechargeable battery was invented by the French physicist Gaston Plante in 1859, and was called the lead acid cell. This later became the world’s first rechargeable battery and is still in use today in the form of modern car batteries.

The concept behind rechargeable batteries is quite basic and simple. Electrical energy is applied to the battery causing the flow of rechargeable batteries2electrons in the opposite direction from the way they flowed when the battery discharged, restoring the power to the battery. Electrical products and devices with built-in batteries need an adapter to re-charge them. The most common type of rechargeable batteries are nickel-cadmium  and nickel-metal hydride, used for many types of devices such as remote control devices, flashlights, digital cameras and a lot more.
