Batteries – Bringing Power to the People

Have you ever considered how many times in a day you make use of a battery? You pick up your mobile phone and it has a battery, you start your car and the engine fires up because of a battery, you're at a work meeting and your laptop is running off a battery, you look at your wristwatch and it has a battery – you may even have one in your razor or toothbrush.

Batteries are ubiquitous sources of power in our lives and make our daily functioning easier and more convenient. They do also however need to be charged in order to be of use to us. You can purchase rechargeable batteries online via

Count Alessandro Volta was the Italian physicist who bought the wonderful world of battery power to life. Batteries require anodes, cathodes and electrolytes to produce a current involving an electrochemical reaction that moves electrons from negative to positive terminals and come in both non-rechargeable and rechargeable forms.

To restore the charge in the rechargeable battery, energy must be supplied from an external source, for example via a battery charger, that moves the electrons in reverse from positive to negative terminals, thereby restoring the charge.

Lithium-ion (LiOn), nickel-metal hydride (NiMH) and nickel-cadmium (NiCd) batteries are examples of rechargeable batteries. The charging process however is not a hundred percent efficient so gradually charge is lost and the battery will eventually cease to function.
