The Saft LS/LST/LSG ranges are cylindrical primary lithium cells, based on the Lithium-Thionyl chloride (Li-SOCl2) chemistry. Their key features are is the concentric electrodes ("bobbin") construction that enables maximum loading of active materials and corresponding energy.
The LS/LST/LSG cells are designed specifically for long-term (3 to 15 years) applications, featuring a few µA base currents and periodic pulses, typically in the 5-150 mA range.
The ‘C’ cell versions are specially recommended for indoor applications (with temperatures generally lower than +30°C) where they demonstrate an excellent resistance to passivation.
The LS cells are manufactured in France, the LSTs in the UK and the LSGs in China. They differ mostly in minor construction, size and finish details.
