LS17500_datasheet review June 2015

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

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.
