LM 26500 Primary Li-MnO2 cell 3 V lithium manganese dioxide C-size spiral cell Saft’s LM 26500 cell is ideally suited for applications requiring high energy and long operating life, with stable voltage under high discharge rates in –40°C / +85°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) ■■ RoHS and REACH compliant ■■ Made in USA Designed to meet all major quality, safety and environment standards ■■ Safety: UL 1642 and IEC 60086-4 ■■ Transport: UN 3090 and UN 3091 ■■ Quality: ISO 9001, Saft World Class Continuous program Typical Applications ■■ Utility metering ■■ Alarms and security ■■ Tracking systems ■■ GSM/GPRS communication ■■ Radio communications systems ■■ Medical devices Electrical characteristics (Typical values relative to cells stored for one year or less at +30°C max) Nominal capacity (at 150mA +20°C 2.0V cut-off)1 7.4 Ah Open circuit voltage (at +20°C) 3.2 V Nominal voltage (under 1mA at +20°C) 3.0 V Nominal energy (at 150mA +20°C 2.0V cut-off) 20.9 Wh 2 Pulse capability up to 4.0 A Recommended maximum continuous current 2.0 A Operating conditions Operating temperature range3 Storage temperatures Recommended Allowable4 -40°C to +85°C +30°C (86°F) max -55°C to +90°C Physical characteristics Diameter (max) Height (max) Typical weight Li metal content 26.0 mm 51.5 mm 61 g approx. 2.8 g Terminations Available termination suffix CNR 3 PF, 3 PF RP, 4PF FL Other configurations upon request radial tabs radial pins flying leads 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 require specific thermal protection. Consult Saft. 4 Long time storage at high temperature may affect performances.
