EPIRB 3.M20 Primary Li-MnO2 battery 9 V lithium manganese dioxide battery for EPIRBs The EPIRB 3.M20 battery is based on Saft M20 D-size spiral cells with high current and pulse capability. It is ideally suited for the demands of EPIRBs (Emergency Position Indicating Radio Beacons). Benefits ■ High drain / high pulse capability ■ High voltage response, stable even after long dormant periods ■ No voltage delay ■ Low self-discharge compatible with long operating life (less than 1 % per year after 1 year of storage at 20 °C) ■ High energy density ■ Light weight ■ Wide operating temperature range ■ Superior resistance to corrosion ■ Easy integration into EPIRBs Electrical characterisƟcs ■ 3 M20 cells in 3S1P configuration ■ Safe, hermetic cell construction with glass-to-metal seal, safety vent and stainless steel container ■ Non-pressurized cells ■ Protection against abusive conditions with integrated polyswitch and diode ■ Centered tube for secure mounting in EPIRBS ■ Versions without centered tube and different cable configurations available on request ■ Restricted for transport (class 9) ■ Manufactured in Germany Designed to meet all major quality, safety and environmental standards ■ Safety: UL 1642 (File MH 12609) ■ Transport: UN 3090 and UN 3091 ■ Quality: ISO 9001, Saft World Class Continuous program ■ Environment: ISO 14001, RoHS and REACH compliant References (4) Sa Part Number (1) ■ EPIRB (Emergency Position Indicating Radio Beacon) COSPAS-SARSAT, 406 MHz Typical capacity (at +20°C / +68°F, 150 mA discharge rate, 6.0 V 12.6 Ah cut‐off voltage) (1) Open‐circuit voltage 9.9 V Nominal voltage (under 1 mA at +20°C) 9.0 V Nominal energy (at 150 mA, +20°C, 6.0 V cut‐off voltage) 108 Wh 2 A Maximum discharge current (con nuous and pulse) (2) Physical characterisƟcs Length 69.0 mm / 2.72 in Width 64.3 mm / 2.53 in Height 65.0 mm / 2.56 in Typical weight 380 g Terminals Op onal Ba ery casing Shrink sleeve OperaƟng condiƟons Opera ng temperature range ‐ 40°C / + 72°C (‐ 40°F / + 161°F) Storage temperatures Recommended + 35°C (+ 95°F) max.
