Lithium power at your
service
Lithium is a light metal which
exhibits an exceptional specific
capacity (3.86 Ah/gram) and
unique electrochemical
characteristics.
Combining lithium with manganese
dioxide (MnO
2
) powder or low-
freezing point liquid cathode
materials such as thionyl chloride
(SOCl
2
) or sulfur dioxide (SO2),
results in batteries with high
energy, low weight, reduced selfdischarge rate, and ability to
operate under extreme conditions.
Saft’s lithium products
3 lithium chemistries are currently
available:
• Lithium-thionyl chloride
(Li-SOCl
2
) in LS/LST/LSX/LSH
3.6 V cells,
• Lithium-sulfur dioxide (Li-SO
2
) in
G/LO 3.0 V cells,
• Lithium-manganese dioxide
(Li-MnO
2
) in LM 3.0 V cells.
Saft Lithium batteries
meeting your needs…
For more than 31 years,
Saft has pioneered the
development and production
of primary lithium cells and
battery packs in Europe,
North America and
Asia/Pacific.
Autonomy, power, voltage,
shape, weight, service life,
price... Saft knows how to
tailor battery solutions you
can count on.
…exceeding your expectations
The LS and LST cells are cylindrical
and based on the high-energy
concentric “bobbin” electrode
configuration. They are available in
standard and high capacity “C”
versions, both adapted to low current
applications.
The LSX, LSH, G, LO and LM cells
are also cylindrical but use the
power-optimized “coiled” and
“spiral” electrode constructions.
The Li-SO
cells are available in
2
“SX” and “G” standard versions and
in high pulse capability “SHX”
versions.
The spiral LM cell series is
completed with 3 button cells
aimed at memory back-up.
Corrosion-proof containers,
hermetic sealing based on rugged
glass-to-metal seals and TIG or
laser welds, built-in safety vents
and individual protection fuses are
design features common to most
of Saft’s lithium cells.
The LS/LST/LSX/LSH/G/LO/LM
cells are available as single units
(with different optional finishes) or
assembled within battery packs.
Whatever your application, you will
probably find a Saft lithium battery
able to meet your particular
requirements. If not, custom-made
solutions can be developed within
your time-to-market constraints.

LS/LST/LSX/LSH cells.
– Above 2 V for LO/G/LM cells.
• Wide current capability
range
From a few microamperes
base current for the LM buttons
and small LS/LST cells to more
than 10 A pulses for some LO, G,
and LM cells.
• Wide operating
temperature range
From – 60°C up to +85°C
depending on cell type, current

• Disposal
According to local regulations.
• Adequate safety
Most of Saft’s lithium cells are
UL (Underwriters Laboratories)
recognized, non-restricted
for transport and EN 50020
approved. Most battery packs

Army standards.
• Storage
The storage area should be
clean, cool (not exceeding
+30°C), dry and ventilated.
*Primary cells and batteries are not rechargeable.
“C” cell versions are recommended for use in cool environments, typical of indoor applications. They yield higher voltage
during pulsing at temperature not exceeding repeatedly +55°C.
“SHX” cell versions offer superior pulse capability for discharges not exceeding the declared voltage cut-off.
Key features
Saft primary lithium chemistries: specific qualities
Saft lithium cell series: performance data
Data given on following pages relates to batteries aged up to 12 months and properly stored. Consult Saft regarding
specific pulse conditions or usage following prolonged storage and/or exposure to extreme temperatures.
- Nominal capacity at +20ºC and 2 V discharge cut-off (continuous current).
- Maximum recommended continuous current:
- LS/LST/LSX bobbin and coiled cells : the current providing 50% of the nominal capacity at +20ºC and 2 V cut-off.
- LSH/G/LO/LM spirals : the above definition or the current that keeps the cells self-heating within safe limits,
whichever is smaller.
- Maximum recommended pulse current : varies according to pulse characteristics (duration, frequency), temperature
conditions, cell storage conditions prior to usage and the application’s acceptable minimum voltage. The use of parallel
capacitor to enhance the voltage at the beginning of pulses might be recommended. Consult Saft.
- Transport status: according to UN model Regulations Ref. ST/SG/AC.10/1 Revision 13 (2003) and Manual of Tests
and Criteria Ref. ST/SG/AC.10/11 Revision 3, Amendment 1
“Lithium Batteries” – 2002.
