Primary lithium battery
G 52/3
3.0 V Primary lithium-sulfur dioxide (Li-SO2)
High drain capability
C-size spiral cell
Benefits
w High and stable discharge voltage
w High pulse capability
w Performance not affected by cell
orientation
w Long storage possible before use
w Ability to withstand extreme
temperature
Key features
w Low self-discharge rate
(less than 2 % after 1 year of
storage at + 20ºC)
w Hermetic glass-to-metal sealing
w Built-in safety vent
(at the negative end of the cell)
w Restricted for transport (class 9)
w Meets shock, vibration and other
environmental requirements of
military specifications
w Made in UK
Main applications
w Radiocommunications and other
military applications
w Sonobuoys
w Life jacket lights
w Professional electronics
w Rescue devices

Operating temperature range
(Operation above ambient T may lead to reduced capacity and lower
voltage readings at the beginning of pulses. Consult Saft)
