Lithium Coin Cells are small discs that are very small and very light, great for small, low-power devices. They're also fairly safe, have a long shelf life and fairly inexpensive per unit. However, they are not rechargeable and have high internal resistance so they can't provide a lot of continuous current: 0.005C is about as high as you can go before the capacity is seriously degraded. However, they can provide higher current as long as its 'pulsed' (usually about 10% rate).
These types of batteries are commonly used in small electronic devices such as watches, calculators, and remote controls. They are also used in certain types of hearing aids and other medical devices. One of the main advantages of lithium button cells is that they have a long shelf life and can retain their charge for several years. Additionally, they have a relatively low self-discharge rate, which means that they will lose less of their charge when not in use.
The typical Voltage of Lithium button cells is 3V, and have a relatively high energy density, which means they can store a lot of energy in a small space. They also typically have a high capacity, so they can power a device for a long time before needing to be replaced.
However, it is important to note that all batteries will eventually run out of power, and it's important to recycle the battery properly when it's no longer in use. Some lithium button cell are hazardous material so check with the recycle center before disposing it.
