Primary Li-MnO2 battery MIRA battery 30 V lithium manganese dioxide (Li-MnO2) battery Saft’s MIRA battery is used as power source for the MIRA night vision system, which is a part of the missile system MILAN. It is also suitable for other military and civil applications with high power needs in -40°C/+72°C environment. Benefits High drain and pulse capability High voltage response, stable even after long dormant periods No voltage delay Low self-discharge compatible with long shelf-life of 10+ years (less than 1% after 1 year of storage at + 20 °C) High energy density Superior resistance to corrosion Key features Twenty M 19 HR cells with spiral design in 10S2P configuration Safe, hermetic and non-pressurized stainless steel cell construction with glass-to-metal seal and safety vent Integrated state-of-charge indicator with LED display and push button Short-circuit proof due to integrated polyswitch Charge protection diode Restricted for transport (class 9) Manufactured in Germany Designed to meet all major quality, safety and environment standards Safety: UL 1642 (File MH 61234), IEC 60086-4 Military: VG 96915-173 (German military standard) Transport: UN 3090 and UN 3091 Quality: ISO 9001, Saft World Class continuous program Environment: ISO 14001, RoHS and REACH compliant Typical applications Night vision system MIRA Emergency supply in submarines Data logger in stratospheric balloons “Power pack” for various needs Saft 12, rue Sadi Carnot 93170 Bagnolet-France Tel.: +33 1 49 93 19 18 www.saftbatteries.com Electrical characteristics (Typical values related to batteries stored up to one year at + 30 °C max) Typical capacity (at 500 mA, +20°C/+70°F, 18.0 V cut-off) (1) Open circuit voltage Nominal voltage (under 1 mA at +20 °C) Nominal energy (at 500 mA, +20 °C, 18.0 V cut-off) (1) Maximum continuous discharge current (2) Operating conditions Operating temperature range Storage temperatures Physical characteristics Length Width Height (max) Battery case Terminals (4) Battery weight Li metal content Recommended Allowable (3) -40°C/+72 °C (-40°F/+161°F) +35°C (+95°F) max. -55°C/+72°C (-67°F/+161°F) 184 mm / 7.24 in 72 mm / 2.83 in 133 mm / 5.24 in Plastic hard case Resilient sockets (corrosion resistant) 2700 g 66 g References Saft Part No. (4) NSN (NATO Stock No.) (1) (2) (3) (4) 21.0 Ah 33.0 V 30.0 V 590 Wh 4.6 A 4409250141 6135-12-329-3740 Can vary depending on current drain, temperature and cut-off voltage.
