Primary lithium battery LO 40 SX
3.0 V Primary lithium - sulfur dioxide (Li-SO2) High drain capability 2/3 “Thin” D- size spiral cell
Benefits • High and stable discharge voltage • High pulse capability • Performance not affected by cell
orientation • Long storage possible before use • Ability to withstand extreme
temperature
Key features • Low self-discharge rate
(less than 3 % after 1 year of storage at + 20ºC) • Hermetic glass-to-metal sealing • Built-in safety vent (at the negative end of the cell) • UL Component Recognition (File Number MH 15076) • Meets shock, vibration and other environmental requirements of military specifications • Restricted for transport (Class 9) • Made in the USA
Main applications • Radiocommunications and other
military applications • Automotive telematics

Handling precautions • Cell is pressurised at ambient
temperature. • Do not puncture, open or mutilate. • Do not obstruct the safety vent
mechanism. • Do not short circuit or charge. • Do not expose to fire or
temperatures above + 70ºC (+158ºF).
