Week 9 - Battery 12V

Some review for type lead acid battery 12V 

12 volt Batteries

12v batteries have variety of uses in our daily life. From consumer electronics to robotics, from health care products to industries, almost every second device we use has one battery or the other. Battery have become an indispensable part of our lives.

This entire power requirement means that we need a robust, portable and an efficient source of power. There are a couple of factors one has to look out while choosing the type of 12v battery. It is because a twelve volt battery can be of many types, sizes, form factors, and materials. 12 volt is just the rating of the battery and it does not specify something physical. Batteries are also available in other voltage ratings such as 24, 9 and 5 volt. It’s rather a quantity. There are many types of batteries depending upon the construction.

 

Lead-acid batteries

Lead-acid batteries were invented in 1859 and are the oldest form of rechargeable battery still in use. They've been used in all types of cars -- including electric cars since the 19th century. Lead-acid batteries are a kind of wet cell battery and usually contain a mild solution of sulfuric acid in an open container. The name comes from the combination of lead electrodes and acid used to generate electricity in these batteries. The major advantage of lead-acid batteries is that, after having been used for so many years, they are well understood and cheap to produce. However, they do produce dangerous gases while being used and if the battery is overcharged there's a risk of explosion.

12 volt lead acid batteries

One of the most common type of 12V battery is the 12v lead acid battery. It is a dc battery with lead terminals and an acid, usually hydrochloric acid is used as an electrolyte in lead acid battery. It is the battery of choice for cars, trucks, tanks, uninterrupted power supplies and other vehicles. 12V lead acid battery is used in cars as there is no risk of handling in cars. 12volt lead acid battery is also used in battery banks and backup systems at power sensitive systems, such as telecom switches, like another 12v dc because it is a source of dc 12v power.  Lead acid 12V battery is rarely used in home appliances and uses. For example, computer UPS' rarely use lead acid battery as it is not very easy to handle and can cause potential hazards, such as a fire etc. Home users generally prefer a solid state battery such as the one used in dry cells over 12v lead acid batteries or rechargeable battery which provides 12volt power. Those are found in torch lights, calculators, watches, clocks and toys.
