In today's world most of the equipments that we use ranging from cell phones to cameras need batteries to work. With the advancement in technology there has been a shift from the old conventional batteries to the more advanced lithium batteries.
That said before you buy the batteries it is better to know what kind of battery is qualified for the equipment that you have. Generally all the manufactures include this advice on the equipment itself. CR2032 lithium batteries are also such batteries which are used in a lot of equipments. The other most common type of batteries is the alkaline batteries and the nickel cadmium batteries.
You must be wondering what this CR2032 means. C stands for manganese dioxide. There are other batteries which have S as the initial character. The meaning of S is silver oxide.
The next is the letter R which denotes the round shape. Next in the name of the battery are the numerical digits which are the 2032. The first two digits that are the 20 means the diameter of the battery is 20mm and 32 means 3.2mm in height. This is known as the electromechanical method of naming.
Now each battery has an anode and a cathode to have the flow of current. In a lithium battery it is the lithium which is the anode and the cathode is the manganese dioxide. The batteries have a long life. The life of these batteries is about ten years. As a precaution these batteries can get damaged by overheating so make sure to remove them from the device after long usage.
