Primary lithium batteries
3.0 V Primary lithium - sulfur dioxide (Li-SO2)
Very high drain and pulse capability
“Thin” D - size spiral cell
• High and stable discharge voltage
• Superior pulse capability
• Performance not affected by cell
• Long storage possible before use
• Ability to withstand extreme
Key features
• Low self - discharge rate
(less than 3% after 1 year of
storage at + 20°C)
• Hermetic glass-to-metal sealing
• Built-in safety vent
(at the negative end of the cell)
• Restricted for transport (class 9)
• UL Component Recognition
(File Number MH 15076)
• Meets shock, vibration and other
environmental requirements of
military specifications
• Made in the USA
Main applications
• Radiocommunications and other
military applications
• Beacons and Emergency Location
• Sonobuoys
