Saft LSH20 primary Lithium cell, is based on the Lithium-Thionyl chloride (Li-SOCl2) chemistry. The LSH20 key features are the concentric electrodes (bobbin) construction that enables maximum loading of active materials and corresponding energy. The LSH20 cell is designed specifically for long-term (3 to 15 years) applications, featuring a few UA based currents and periodic pulses, typically in the 5-150 mA range.
