M 20 EX SV
Primary Li-MnO2 cell
3 V lithium manganese dioxide D-size spiral cell certified for ATEX applications
Saft’s M 20 EX SV cell is ideally suited for
applications requiring high energy and
long operating life, with stable voltage
under high discharge in - 40°C / + 72°C
environment. The cell is certified according
to ATEX for use in potentially explosive
atmospheres.
Benefits
■
■
■

■
High drain / high pulse capability
High voltage response, stable during
most of the lifetime of the application
even after long dormant periods
High capacity and very high pulse capability
Low self-discharge compatible with
long operating life (less than 1% after
1 year of storage at + 20°C)
ATEX certified
Superior resistance to corrosion
Low magnetic signature

Dependent upon current drain, temperature and cut-off.
Limitation of the max. current to a lower level, e.g. by a series resistor, may be necessary depending on the electrical properties
of the device and the desired level of protection (ia, ib, ic) and the explosion group (IIA, IIB, IIC).
(3)
To maintain cell heating within safe limits. Battery packs may imply lower level of maximum current and may request specific
thermal protection. Consult Saft.
(4)
Long time storage at high temperature may affect performances. Consult Saft.
