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 maximum current pulse capability and electrolyte formula for excellent performance in the cold. They are designed specifically for applications featuring continuous currents in the 0.1-5 A range, with superimposed pulses as high as 5 A.
Saft-branded LM cells are manufactured in the USA.
Friwo-branded M cells are made in Germany.
