Adafruit CR2032 Lithium Coin Cell Battery

This non-rechargeable coin cell is CR2032 sized, measuring 20mm in diameter and 3.2mm in thickness. It provides a nominal voltage output of 3V, initially starting at 3.2V and gradually decreasing to 2.5V during use.With a capacity of 220mAh at a constant draw of 0.2mA, this battery is designed for consistent performance. It's ideal for low-drain applications, but variations in drain rates may affect the capacity, so consulting the datasheet is recommended for specific usage scenarios.Perfectly compatible with our sewable coin cell holder, it's a practical choice for wearable tech or compact electronic projects where reliability is key.
