CR1220 3V Lithium Coin Cell Battery for Mini Remote Controls, RTC, and Wearables

Product Description The CR1220 is one of the smallest 3V lithium coin cells available, specifically engineered for ultra-compact electronic devices. With a tiny 12.5mm diameter and a slim 2mm profile, it is the standard power source for small-scale Real-Time Clock (RTC) modules, miniature laser pointers, car key fobs, and medical devices like digital thermometers. Despite its miniature size, it utilizes high-density lithium technology to provide a stable voltage and a long shelf life, making it a reliable choice for critical memory backup and low-power portable electronics.

Key Features

• Ultra-Miniature Footprint: Ideal for space-constrained designs where even a CR1620 is too large.

• Stable 3V Output: Delivers a consistent voltage throughout its discharge cycle, ensuring the accuracy of timing and sensor circuits.

• Long Shelf Life: Retains nearly all its capacity for up to 10 years when stored properly, thanks to a very low self-discharge rate.

• Lightweight: At under 1 gram, it is perfect for weight-sensitive wearable tech and micro-robotics.

• High Temperature Resistance: Operates reliably across a wide range of environmental conditions.
