A dry cell battery is one of the most used kinds of batteries worldwide. Dry cell batteries are actually pretty common that you will be surprised how it actually affects your everyday life, although you're not aware of it. A dry cell battery is a kind of battery that goes in your laptop for self usage and non-plugged works. The batteries can actually be recharged through a specific wire in a regular electric plug. A, C, 9-volt and most watches are equipped with a dry cell battery. A wet cell battery, on the other hand, are those that are used in cars.
The first dry cell battery was invented in as early as 1885 by Sakizou Yai. Since then, dry cell batteries have become a much used kind of battery. These batteries are easily charged and relatively cheap, which is good news for the human race.
Dry cell batteries have the same components even though they come in different sizes. The center of a dry cell battery has a rod that is named cathode. This cathode is usually made up of a metal or sometimes, graphite which is enclosed by an electrolyte paste. The electrolyte paste and the cathode are covered in cardboard or paper.
Some of these cells are covered with a metal cylinder that is called anode, usually, made up of alkaline or zinc. You can see in a dry cell battery that the anode has two terminals --- one that is positive and the other negative. A chemical reaction then takes place when the battery’s terminal is connected with a load. But after some time, the battery’s chemicals can no longer produce a charge. That's the time when you will need to replace it.
Dry cell batteries should be recycles or disposed properly. All batteries have chemicals which can be harmful to human health and the environment. There are many stores or even environmental conscious and concerned companies and groups that accept used or damaged batteries for proper disposal. It is always best to use rechargeable batteries to save money, avoid unnecessary harmful toxins and help preserve the environment.
