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
