Primary lithium battery
LS 14250W
3.6 V Primary lithium-thionyl chloride (Li-SOCl2)
High energy density
1⁄2 AA-size bobbin cell
For demanding environments up to + 95ºC
For applications requesting superior
voltage response and operating life
in Widely fluctuating temperature
environments up to + 95ºC.
Benefits
l High voltage, stable during most
of the application’s lifetime
l Superior voltage readings after
exposure at elevated temperature
l Voltage readings during pulsing
moderately affected by
T fluctuations
l Low self-discharge rate
(less than 1 % per year of
storage at + 20ºC)
l Easy integration into compact
systems
l Superior resistance to
atmospheric corrosion
Key features
l Stainless steel container
and end caps
(low magnetic signature)
l Hermetic glass-to-metal sealing
l Non-flammable electrolyte
l Non-restricted for transport
Main applications
l Electronic toll collection
l Utility metering
l Automatic meter reading
l Alarms and security devices
l Tracking systems
l Automotive electronics
l Professional electronics
Electrical characteristics
(typical values relative to cells stored for one year or less at + 30ºC max.)
Nominal capacity 1.20 Ah
(at 1 mA + 20ºC 2.0 V cut-off. The capacity restored by the cell varies
according to current drain, temperature and cut-off)
Open circuit voltage (at + 20ºC) 3.67 V
Nominal voltage (at 0.1 mA + 20ºC) 3.6 V
Pulse capability : Typically up to 100 mA (100 mA/0.1 second pulses,
drained every 2 mn at + 20ºC from undischarged cells with 10 µA base
current, yield voltage readings above 3.0 V. 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.
Consult Saft)
Maximum recommended continuous current 35 mA
(Higher currents are possible, consult Saft)
Storage (recommended) + 30ºC (+ 86ºF) max
(for more severe conditions, consult Saft)
Operating temperature range - 60ºC/+ 95ºC
(Operation above ambient T may lead to reduced capacity and (- 76ºF/+203ºF)
lower voltage readings at the beginning of pulses. Consult Saft)

Storage
l The storage area should be
clean, cool (preferably not
exceeding + 30ºC), dry and
ventilated.
Warning
l Fire, explosion and burn hazard.
l Do not recharge, short circuit,
crush, disassemble, heat above
100ºC (212ºF), incinerate,
or expose contents to water.
l Do not solder directly to the cell
(use tabbed cell versions instead).
