LS 17500 Primary Li-SOCl2 cell 3.6 V lithium thionyl chloride A-size bobbin cell Saft’s LS 17500 cell is ideally suited for long-term applications (typically from 5 to 20+ years), featuring low base currents and periodic pulses. Benefits High capacity and high energy (1139 Wh/l and 592 Wh/kg) High voltage response, stable during most of the lifetime of the application Wide operating temperature range (- 60 °C / + 85 °C) Low self-discharge compatible with long operating life (less than 1% after 1 year of storage at + 20 °C) Superior resistance to corrosion Low magnetic signature Key features Bobbin construction Well controlled passivation Hermetic construction with glass-tometal seal Stainless steel container Non-flammable electrolyte Non restricted for transport RoHS and REACH compliance Made in France, China, UK Designed to meet all major quality, safety and environment standards Safety: UL 1642, IEC 60086-4 ATEX: IEC 60079-11 part 10.5 (T3 rating at + 40 °C) Transport: UN 3090 and UN 3091 Quality: ISO 9001, Saft World Class continuous program Electrical characteristics (Typical values relative to cells stored up to one year at + 30 °C max) Nominal capacity (at 3 mA, + 20 °C, 2.0 V cut-off) (1) Open circuit voltage (at + 20 °C) Nominal voltage (at 0.3 mA, + 20 °C) Nominal energy Pulse capacity (2) Maximum recommended continuous current Operating conditions Operating temperature range (3) Storage temperatures Physical characteristics Diameter (max) Height (max) Typical weight Li metal content -60 °C / + 85 °C (- 76 °F / + 185 °F) Recommended (4) + 30 °C (+ 86 °F) max 17.13 mm (0.67 in) 50.9 mm (2.00 in) 21.9 g (0.8 oz) approx.. 0.9 g Termination Available termination suffix CN, CNR 2 PF, 3 PF, 3 PF RP, 4 PF CNA FL Other configurations upon request Typical applications Utility Metering Internet of Things Alarms and security Medical devices Tracking systems Professional electronics 3.6 Ah 3.67 V 3.6 V 12.96 Wh up to 250 mA 100 mA (1) (2) (3) (4) radial tabs radial pins axial leads flying leads Dependent upon current drain, temperature, cut-off and cell orientation. Under 0.1 second pulses, drained every 2 minutes at + 20 °C from undischarged cells with 10 µA base current, yield voltage readings above 3.0V after initial stabilisation. The readings may vary according to the pulse characteristics, the temperature, and the cell’s previous history. Fitting the cell with a capacitor may be recommended in severe conditions or for high pulse currents. Consult Saft. Operation above ambient temperature may lead to reduced capacity and lower voltage readings. Consult Saft. For more severe conditions, consult Saft.
