Primary lithium battery LM 33550 3 V Primary lithium-manganese dioxide (Li-MnO2) High power D-size spiral cell For applications requesting excellent voltage response and operating life in - 40°C/+ 70°C environments Benefits • High voltage response, stable during most of the lifetime of the application • High drain/pulse capabilty • Minimum voltage delay after long dormant periods • Competitive capacity at high current and low temperature • Easy integration into compact systems • Low self-discharge rate (less than 2% after 1 year of storage at + 20°C) Key features • Steel container • Hermetic glass-to-metal sealing • Built-in safety vent • Non-corrosive electrolyte • Restricted for transport (Class 9) • Made in the USA Main applications • Radio communication • Measuring equipment • Marine equipment • ELTS, EPIRBS, etc. January 2011 Cell size reference R20 - D Electrical characteristics (Typical values relative to cells stored for one year or less at + 30°C max.) Nominal capacity (at 250 mA + 20°C 2.0 V cut-off. The capacity restored by the cell varies according to current drain, temperature and cut-off). 13 Ah Open circuit voltage (at + 20°C) 3.2 V Nominal voltage (under 1 mA at + 20°C) 3.0 V Pulse capability : Typically up to 8 A (The voltage readings may vary according to the pulse characteristics, the temperature, and the cell’s previous history. Fitting the cell with a capacitor may be recommended in severe conditions. Consult Saft.) Maximum recommended continuous current (To maintain cell heating within safe limits) Storage (recommended) (for more severe conditions, consult Saft) Operating temperature range (Operation below ambient T may lead to reduced capacity and lower voltage readings) 4A + 30°C (+ 86°F) max - 40°C /+ 70°C Physical characteristics (with sleeve) Diameter (max) 34.2 mm (1.35 in.)
