Tadiran TL-4903 size AA Lithium Battery 3.6V - non Rechargeable Tadiran Batteries

Tadiran TL-4903 size AA Lithium Battery 3.6V - non Rechargeable 100% ORIGINAL 100% BRAND NEW Tadiran TL-4903 made in Israel Lithium Battery 3.6V non Rechargeable Lithium Thionyl Chloride size AA 0.57" Dia x 1.99" H 14.5mm x 50.5mm The Tadiran TL-4903 is a high-performance Lithium Thionyl Chloride (LiSOCl2) battery, specifically designed for long-term use in industrial and professional electronics. Unlike standard household batteries, this is a specialized power source known for its "wafer" shape and exceptional shelf life. Key Technical Specifications Voltage: 3.6V Capacity: 1.2A (1200 mAh) Size: AA (Wafer construction) Operating Temperature: -55°C to +85°C Self-Discharge Rate: Less than 1% per year at room temperature. Why It’s Unique Longevity: These batteries are built to last 10 to 20 years in low-drain applications. They are often the "set it and forget it" choice for critical systems. High Energy Density: It packs a significant amount of power into a small AA-sized frame, though it is designed for low-current pulses rather than high-drain devices like motor-driven tools. Hermetic Sealing: The glass-to-metal seal ensures the battery doesn't leak, even under extreme environmental stress or pressure changes. Common Applications You will typically find the TL-4903 in equipment where losing power or changing batteries frequently is not an option: Memory Backup (CMOS): Keeping clock settings and BIOS data alive in industrial computers and CNC machines. Utility Meters: Powering smart gas, water, and electricity meters. Security Systems: Used in wireless sensors and alarms. Medical Devices: High-reliability power for portable monitoring equipment.
