The Saft LO/G cylindrical primary lithium cells are based on Lithium-Sulphur dioxide (Li-SO2) chemistry and feature very high surface area spiral electrodes for maximum current pulse capability. They are designed for applications featuring continuous currents in the 0.1-5 A range, with superimposed pulses as high as 20 A.

The LO cell models are manufactured in the USA and the G cell models are manufactured in the UK.

 

Construction features

  • spiral electrodes
  • nickel-plated steel containers
  • hermetic and sturdy glass-to-metal sealing
  • built-in safety vent 
  • available as individual batteries (size ½ AA to ‘Fat’ DD; with or without tabs) or multi-cell battery packs

 

Main applications

  • military radiocommunication
  • sonobuoys and other underwater applications
  • emergency location transmitters beacon (ELTs, EPIRBs)
  • professional electronics
  • cardiac defibrillators

 

Benefits

  • high operating voltage, stable during most of the application lifetime
  • wide operating temperature range (-60°C to +70°C)
  • good resistance to passivation
  • non-flammable (but corrosive) pressurized electrolyte, quickly expelled in case of venting
  • less than 3% capacity loss during storage at ambient temperature before use
  • released capacity independent from cell orientation
  • unrivalled pulse capability
  • Compliance with the European directive RoHs
  • Excelent time-tested (25 years of mass production experience) safety records in many demanding military applications
