AA Lithium Battery

Energizer  Lithium AA (L91) is a high-performance, lithium-iron disulfide (Li/FeS₂) primary battery designed for medical devices requiring long life, extreme temperature tolerance, and high-drain capability. Key specifications: ANSI 15-LF, IEC-FR14505 (FR6) designation; 1.5V nominal voltage; 3000-3600 mAh capacity; 2.5A continuous / 4.0A pulse discharge; 15g weight; -40°C to 60°C operating range; and 25-year shelf life at 21°C. Features ATEX intrinsically safe certification (Ex ia IIC Ga) for use in explosive atmospheres, including oxygen-rich medical environments. Contains less than 1 gram of lithium per cell and zero added mercury. For clinicians, the L91 is indicated for high-drain, extreme-temperature, long-storage, or hazardous-location medical applications. Ingestion requires immediate medical attention (800-498-8666).
