M 20 HR Primary Li-MnO2 cell 3 V high power lithium manganese dioxide D-size spiral cell Saft’s M 20 HR cell is ideally suited for applications requiring high discharge, continuous or pulse power with stable voltage under high discharge in - 40°C / + 72°C environment. 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 at high current and low temperature Low self-discharge compatible with long operating life (less than 1% after 1 year of storage at + 20°C) 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) Transport: UN 3090 and UN 3091 Military: VG96915 part 2 and part 154 Quality: ISO 9001, Saft World Class Continuous program Environment: ISO 14001 Typical applications ■ ■ ■ ■ ■ ■ ■ Radio communications Alarms and security systems ELTs, EPIRBs Tracking systems M2M communication Medical devices Oil & gas applications Electrical characteristics (Typical values relative to cells stored up to one year at + 30°C max) Nominal capacity (at 0.5 A, + 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 0.5 A, + 20°C, 2.0 V cut-off) Pulse capacity (2) Recommended maximum continuous discharge current (3) 11.5 Ah 3.2 V 3.0 V 32 Wh up to 10.0 A 4.0 A Operating conditions Operating temperature range (4) Recommended Storage temperatures Allowable (5) - 40°C / + 72°C (- 40°F / + 161°F) + 30°C (+ 86°F) max - 55°C to + 85°C (- 67°F / + 185°F) Physical characteristics Diameter (max) Height for the tabbed version (max) Height for the version with +/- end caps (max) Typical weight Li metal content 34.2 mm (1.35 in) 61.5 mm (2.42 in) 62.5 mm (2.46 in) 117 g approx. 3.6 g Dependent upon current drain, temperature and cut-off. Dependent upon pulse characteristics, temperature, cell history and application. Higher rates are available under certain circumstances (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) Operating temperatures up to + 85°C can be achieved. Consult Saft.
