CMOS Battery CR2032
The CR2032 CMOS Battery is a coin cell battery primarily used to power the CMOS (Complementary Metal-Oxide-Semiconductor) chips in electronic devices. These chips are responsible for maintaining system settings such as date and time, even when the device is powered off. The CR2032 is a popular choice due to its compact size, long shelf life, and reliability. It is commonly found in motherboards, clocks, calculators, remote controls, and various other small electronic devices.
Key Features:
- Voltage: 3V
- Capacity: Around 220mAh
- Diameter: 20mm
- Thickness: 3.2mm
- Chemistry: Lithium
- Long Shelf Life: Typically lasts up to 10 years or more in storage.
- Leak-Proof Design: Protects devices from battery leakage and damage.
- Wide Compatibility: Suitable for a wide range of devices including computers, watches, and more.
How It Works: The CR2032 battery is used in devices to provide a continuous 3V power supply to circuits that require minimal energy. When a device is turned off, the CMOS battery ensures that essential settings like the system clock or other memory parameters are preserved, allowing the device to function correctly when it’s powered back on.
