The Saft LM/M cylindrical primary lithium cells are based on lithium-manganese dioxide (Li-MnO2) chemistry. They feature high surface area spiral electrodes for high power and maximum current pulse capability and an electrolyte formula for excellent performance in low temperatures. They are designed specifically for applications featuring continuous currents in the 0.1-5A range, with superimposed pulses as high as 5A. They deliver minimal voltage delay, even after long-term storage in uncontrolled temperature environments.
