3v button cell
The 3V button cell is a compact, high-performance power source that combines reliability with versatility in a small form factor. These coin-shaped batteries utilize lithium-based chemistry to deliver a consistent 3-volt output, making them ideal for various electronic devices. The battery's construction features a sealed, airtight design that prevents leakage while ensuring a long shelf life of up to 10 years. With a diameter typically ranging from 12mm to 24mm and a height of 1.6mm to 3mm, these cells pack substantial power in a minimal footprint. The internal composition includes a lithium anode, manganese dioxide cathode, and an organic electrolyte, all precisely engineered to maintain stable voltage throughout the discharge cycle. These cells excel in applications requiring low continuous current draw while maintaining the capability to handle occasional high-current pulses. Common applications include watches, calculators, car key fobs, medical devices, and various electronic measurement instruments. The cells operate effectively across a wide temperature range, typically from -20°C to 60°C, ensuring reliable performance in diverse environmental conditions. Their non-rechargeable nature is offset by their exceptional energy density and minimal self-discharge rate, typically less than 1% per year when stored properly.
