Batteries - Button/Coin Cell - Lithium

About

Lithium button and coin cell batteries offer reliable, long-lasting power in a very compact form factor. They are commonly used in devices like watches, calculators, medical devices, and memory backup modules. These cells typically use lithium chemistry with a nominal voltage around 3V. Their energy density is significantly higher than alkaline coin cells, which makes them well-suited for memory retention or low‑drain electronics that benefit from long shelf life. Lithium coin cells deliver consistent, dependable power for small devices where size and longevity are critical, and their compact construction makes them a practical choice for a wide range of specialized electronics.
