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 Key features ■ ■ ■ ■ ■ ■ ■ ■ Spiral construction Hermetic construction with glass-to-metal seal Stainless steel container Integrated safety vent Non-corrosive electrolyte Non-pressurized at room temperature Restricted for transport (Class 9) Made in Germany Designed to meet all major quality, safety and environmental standards ■ ■ ■ ■ ■ ■ Safety: UL 1642 (File MH 12609) IEC 60079-0, IEC 60079-11 Transport: UN 3090 and UN 3091 Military: VG96915 part 2 and part 154 Quality: IEC 60086-4, ISO 9001, Saft World Class Continuous program Environment: ISO 14001 Typical applications ■ ■ ■ ■ ■ ■ Smart gas meters Gas and oil tank level monitoring Leak detectors Portable gas detectors Petrochemical facilities Mining applications Electrical characteristics (Typical values relative to cells stored up to one year at + 30°C max) Nominal capacity (at 150 mA, + 20°C, 2.0 V cut-off) (1) Open circuit voltage (at + 20°C) Nominal voltage (under 1 mA at + 20°C) Nominal energy (at 150 mA, + 20°C, 2.0 V cut-off) Pulse capacity (2) Recommended maximum continuous discharge current (2) (3) Operating conditions Operating temperature range Recommended Storage temperatures Allowable (4) ATEX properties Cell marking EC-type examination certificate nb Short circuit current (max) Ri (min) Temperature rise (max) Temperature class Physical characteristics Diameter (max) Height for the tabbed version (max) Typical weight Li metal content + 20°C (+ 68°F) 57 A 45 m Ω + 107 °C T4 12.4 Ah 3.2 V 3.0 V 35 Wh up to 8.0 A 3.5 A - 40°C / + 72°C (- 40°F / + 161°F) + 30°C (+ 86°F) max - 55°C to + 90°C (- 67°F / + 194°F) II 2G BVS 12 ATEX E 026 U + 40°C (+ 104°F) + 70°C (+ 158°F) 64 A 85 A 41 m Ω 35 m Ω + 112°C + 118°C T4 T4 34.2 mm (1.35 in) 61.5 mm (2.42 in) 115 g approx. 3.5 g 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.
