Lithium Coin Cell Battery

These non-rechargeable lithium coin cells provide long-life 3V power for low-drain uses like RTCs, key fobs, or wearables—CR2032 (225mAh) and smaller CR1220 (35mAh). Perfect for first-year engineering students backing up Arduino clocks or sensors.

CR2032: 20×3.2mm, ~10-year shelf life; CR1220: 12.5×2.0mm for ultra-compact spots. 220mAh (CR2032) lasts months in sleep mode; half-tab versions fit retainers.
