Before we go into the details of 12-volt battery, let's briefly understand how a standard battery works?
A battery, defined in the dictionary, is a device that converts chemical energy directly into electrical energy. The first ever chemical battery - voltaic pile - was developed by Italian physicist, Alessandro Volta (1745-1827). The unit of measurement of the battery is Voltage (that is measured in Volts). We can divide batteries into two main categories: Primary or non-rechargeable batteries and Secondary or rechargeable batteries. Examples of Primary batteries are like Alkaline, Lithium and Secondary batteries are like Lead-acid, Lithium-ion battery.
The 12-Volt Battery
The 12-volt battery can be described as one most versatile batteries existing in the word of electronics. In many ways, the 12-volt battery is one of the most diverse batteries in nature. It can be found in various shapes, sizes and weights - sometimes as small as a regular AA battery, like the one in your wall-clock!
The 12-Volt battery is used in outdoor applications that require larger amounts of energy to operate. However, it is sometimes recommended to use a rechargeable 12 Volt battery if the product is being used very frequently. Non-rechargeable 12-volt batteries can become expensive if they need to be purchased often. Long term cost-effectiveness of the 12-volt battery can be determined by the product type and usage frequency.
Manufacturers, over time, have attempted to reduce the size of the 12-volt battery to a portable one to run applications like fish-finders. The 12 Volts battery also finds common usage in transport applications like cars, motorcycles, boats. Most vehicles use rechargeable 12-volt batteries as the electricity being generated by the battery is only required for ignition.
The sizes of a 12-volt battery can greatly vary based on the ampere (measure of the amount of electric charge passing a point per unit time) per hour that they must generate. They can be voluminous and heavy, like those found in vehicles or relatively smaller like batteries found in children's toys.
The 12-volt battery has various kinds, suited to an application:
• 12-volt sealed lead acid batteries ideal for powering children's ride-on's or mobility use
• 12-volt lithium batteries for powering off-road electric vehicles and high speed motor-sport
• 12-volt solar battery and 12-volt battery charger used to bring up solar-energy run automobiles or personal watercraft
• gel 12-volt battery used in refrigerators, navigation equipment
It is very difficult to list every kind of 12-volt battery or even the usage for each battery, but it is always considered as one of the product that is required in our everyday life.
Hot tip
Always remember that you can increase the life for a battery!
The life of a battery can be increased by storing batteries at low temperatures, like a refrigerator/ freezer! Low temperatures slow down the chemical reactions inside the batteries thus increasing its life-span.
