There are a number of different coin cells that are used for various applications on the market today. Coin cells can be used in excess of five years for low-drain use applications and assure a steady and extremely reliable current. The manganese dioxide that is in the batteries is chemically very stable as the positive material to assure the long service life.
Applications That Use Coin Cells
Coin batteries are used in a broad range of applications, some of which include wrist watches, clocks, PDAs, electronic organizers, computer motherboards, cell phones, cameras, heart monitors and backup power sources for IC memories. In addition, they are used for electronic multifunction calculators, electronic copying equipment and other portable electronics. There are two basic cell types–there are bare cells that are for user-replaceable applications and cells with tab terminals for PC boards.
Lithium Coin Cell Battery
Lithium coin cell batteries are a very popular type. The lithium metal is used as the active anode material or negative electrode. Variations in the cathode material, or positive electrode, and the cell electrolyte result in hundreds of possible combinations and uses for lithium batteries. This type of battery is used in many electronic applications.
A Lithium battery, when stored at room temperature, can give you up to a 10-year shelf life! These batteries have an annual self discharge rate of 1% or less, so their shelf life is much longer than conventional batteries. You can get Lithium and other coin batteries right here online for basically any type of application.
