LIR2032 Coin cell

The LIR2032 is a rechargeable lithium-ion coin cell battery with a nominal voltage of 3.6V and a typical capacity ranging between 40 to 60mAh. Unlike standard non-rechargeable lithium coin cells (like the CR2032), the LIR2032 can be recharged multiple times, making it ideal for applications requiring long-term, sustainable power. Its compact size (20mm diameter, 3.2mm thickness) allows use in small electronic devices such as wearable gadgets, fitness trackers, small medical devices, and memory backup systems. This battery features a low self-discharge rate, ensuring retention of charge during standby periods. The LIR2032 also offers stable voltage output and reliable performance across various temperatures. Proper charging with a compatible lithium-ion charger is essential to maintain battery health and safety.
