SAFT LSH20 Lithium Battery Button Top, D-Size 3.6 Volts

Button Top Pressure Contacts

The Saft LSH cylindrical primary lithium cells are based on Lithium-Thionyl chloride (Li-SOCl2) chemistry and feature high surface area spiral electrodes for maximum current capability.

They are designed for applications requiring continuous currents in the 0.1-1.8 A range, with superimposed pulses as high as 4 A.

Construction features

  • spiral electrodes
  • stainless steel container
  • hermetic and sturdy glass-to-metal sealing
  • built-in safety vents
  • individual cells with 5.5 A non-resettable fuse
  • available as individual batteries (size 1/3 C to D; with or without tabs


  •  High operating voltage, stable during most of the application lifetime
  • Good pulse capability
  • Wide operating temperature range  (-60C to +70C),  +120C for some cell versions
  • Good resistance to passivation 
  • Non-flammable (and non-pressurized at ambient temperature),  inorganic (but corrosive) electrolyte
  • Less than 3% capacity loss per year, during storage at ambient temperature before use
  • Performance independent from cell orientation
  • Up to 25 years of mass production experience
  • Compliant with the European directive RoHS
  • Good safety records
