## Saft M 20 EX SV 2 cell Primary Li-MnO
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 and IECEx for use in potentially explosive atmospheres.
##
- High drain / high pulse capability
- High voltage response, stable during most of the lifetime of the application even after long dormant periods

## Typical applications
- (1) Dependent upon current drain, temperature and cut-off.
- Smart gas meters
- (2) 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).
- Gas and oil tank level monitoring
- Leak detectors
- (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.
- Portable gas detectors
(4) Long time storage at high temperature may affect performances. Consult Saft.
- Petrochemical facilities (5) Owner of the certificate: Friemann & Wolf Batterietechnik GmbH.
- ■ Mining applications (6) During the 3 mΩ short-circuit test according to IEC 60079-11. ~~a~~
