Lithium-Thionyl Chloride - Li-SOCl2 Batteries

Key Features
High operating voltage, stable during most of the application lifetime
Lowest self-discharge for extended shelf life and operating life
Well controlled passivation with limited voltage delay
Some of the highest nominal capacities on the market today
Excellent reliability over extended operating life


The Saft LS range has a “bobbin” construction. The concentric electrodes enable the maximum loading of active materials and correspondingly, maximum energy and lowest self-discharge.

This range is designed specifically for long-term (3 to more than 20 years) applications, featuring a few µA base currents and periodic pulses, typically in the 5-150mA range.

Additional Features

Saft batteries have the following:

  • Excellent resistance to humid environments
  • Low magnetic signature
  • Excellent safety records
  • Up to 25 years of mass production experience
