The CR2477 is a high-capacity 3.6V non-rechargeable lithium coin cell battery, designed for applications requiring long-lasting and stable power in a compact form factor. Measuring 24.5 mm in diameter and 7.7 mm in thickness, the CR2477 offers a larger capacity compared to standard coin cells like CR2032 or CR2450, making it suitable for high-drain or extended-use devices.
This battery typically provides a nominal capacity of 950–1000 mAh, delivering consistent performance throughout its service life. It uses lithium manganese dioxide (LiMnO₂) chemistry, offering high energy density, low self-discharge (less than 1% per year), and excellent temperature stability. Operating within a temperature range of -20°C to +70°C, the CR2477 is ideal for both indoor and outdoor environments.
Commonly used in IoT devices, medical instruments (like glucose monitors), real-time clocks (RTC), sensors, keyless entry systems, industrial equipment, and memory backup applications, this battery ensures long shelf life (up to 10 years) and reliable performance in intermittent or continuous use scenarios.
