Coin Battery Cell

Coin batteries, also known as button cell batteries, are small, round, and typically flat batteries commonly used in various electronic devices such as watches, calculators, key fobs, remote controls, and small medical devices. They are named "coin" batteries due to their shape resembling a coin or button.

Coin batteries usually contain lithium, silver oxide, or alkaline chemistry. They are designed to provide a stable voltage over a long period, making them suitable for low-power devices. However, their capacity is relatively small compared to larger batteries, so they are typically used in applications where space is limited and power consumption is low.
