LS, LSH, LSP

Saft’s LS, LSH and LSP cylindrical primary lithium cells ranges, all based on Lithium-Thionyl chloride (Li-SOCl2) chemistry perfectly suit high-energy and high-voltage requirements in a wide range of temperatures.

The bobbin construction of the LS range enables the maximum loading of active materials and the correspondingly maximum energy. With its remarkably low self-discharge, it perfectly matches long-term (from five to 20 years plus) applications featuring a few µA base currents and periodic pulses, typically in the 5-150 mA range.

The LSH range has a spiral construction and includes specific models that can operate at the very high temperatures found in oil and gas applications, for example. The cells are designed for applications requiring pulses as high as 4 A.
