Lithium thionyl chloride (LiSOCl₂) batteries are pivotal in enabling long-term, maintenance-free operation of smart building sensor networks due to their superior energy density, exceptional shelf life, and reliability in extreme environments. These attributes make them particularly suitable for powering a diverse array of embedded electronic devices within smart infrastructure-including wireless HVAC sensors, high-voltage direct current (HVDC) sensing units, low-power IoT nodes, security and occupancy detectors, structural health monitors, and adaptive lighting or ventilation controllers.This study presents an empirical evaluation of four leading LiSOCl₂ battery brands-EVE, Saft, TEKCELL, and TADIRAN-to assess their real-world performance under varying discharge currents, with direct implications for power circuit design in smart building sensor networks. Despite similar datasheet specifications, our findings reveal substantial discrepancies in actual performance, capacity retention, and degradation characte
