Tdiran TL 5902 1/2AA (copy)

The TL-5902 is a high-performance 3.6V lithium thionyl chloride (Li-SOCl₂) battery, designed for long-term applications requiring high energy density, low self-discharge, and wide operating temperature. Though this is a copy variant, it typically mirrors many of the capabilities of the original Tadiran cell, making it suitable for low-drain devices, memory backup, sensors, PLC systems, and remote equipment.

Features:
• Nominal Voltage of 3.6V for high energy efficiency
• 1/2AA size — compact and ideal for space-constrained applications
• High energy density ensures long runtime
• Low self-discharge rate (<1% per year)
• Wide operating temperature range suitable for industrial use
• Hermetically sealed for leak protection
• Typically used in utility meters, medical devices, and security systems
