The LR41 Alkaline Manganese Dioxide Button Cell Battery is a miniature, non-rechargeable power cell engineered for ultra-compact, low-drain electronic assemblies. The alphanumeric “LR41” designation defines its specific chemical matrix and micro-physical footprint: 7.9 mm in diameter and 3.6 mm in thickness. Due to its tiny cylindrical geometry, it is the primary power source for small medical digital thermometers, mini laser pointers, light-up pocket novelties, localized wearable micro-LEDs, and analog wristwatches.Â
