Batteries - Lithium Primary

About

Lithium primary batteries offer high energy density and long shelf life, making them ideal for devices that need ready-to-go power without frequent maintenance or recharging. Their compact size and strong output make them a popular choice for equipment that must perform reliably over long periods or remain idle for years. These batteries use metallic lithium at the anode and chemistries such as lithium-manganese dioxide or lithium-iron disulfide at the cathode, resulting in a nominal voltage that often ranges from about 3V up to 3.7V per cell. They are non-rechargeable. Once the energy is spent the battery must be replaced, but they maintain their charge very well over long storage periods and are less prone to self-discharge than many rechargeable cells. Because of their high energy density, stable voltage output, and long shelf life, lithium primary batteries are an excellent choice for devices such as smoke detectors, remote sensors, keyless entry modules, and other electronics that benefit from dependable, long-term power without the need for recharge.
