• 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 + 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
military specifications
Made in UK

Electrical characteristics
(typical values relative to cells stored for one year or less at + 30 °C max.)
Nominal capacity
(at 0.08 A + 20°C 2.0 V cut off. The capacity restored by the cell varies
according to current drain, temperature and cut off)
1.70 Ah
Open circuit voltage (at + 20°C)
3.0 V
Nominal voltage
2.8 V
(at 0.1 A + 20°C)
Continuous current permitting 50% of the nominal capacity to be achieved
at + 20ºC with 2.0 V cut off.
1.5 A
Pulse capability : Typically up to 2.5 A.
(The voltage readings may vary 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)
