Primary lithium batteries
3.0 V Primary lithium-sulfur dioxide (Li-SO 2)
High drain capability
1/2 AA - size spiral cell
• High and stable discharge voltage
• High pulse capability
• Performance not affected by cell
• Long storage possible before use
• Ability to withstand extreme
• 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)
• Meets shock, vibration and other
environmental requirements of
• Made in UK

Cell size reference
(typical values relative to cells stored for one year or less at + 30°C max.)
(at 50 mA + 20°C 2.0 V cut of f. The capacity restored by the cell varies
according to current drain, temperature and cut off)
Open circuit voltage (at + 20°C)
(at 0.03 A + 20°C)
Continuous current permitting 50% of the nominal capacity to be achieved
at + 20ºC with 2.0 V cut of f.
Pulse capability : Typically up to 0.4 A.
(The voltage readings may var y according to the pulse characteristics,
the temperature and the cell’s previous history. Fitting the cell with a
capacitor may be recommended in severe conditions. Consult Saft)
(possible without leakage)
+ 30°C (+ 86°F) max
+ 85°C (+ 185°F) max
Operating temperature range
(Operation above ambient T may lead to reduced capacity and lower
voltage readings at the beginning of pulses. Consult Saft)
- 60°C/+ 70°C
