Electrical characteristics
(typical values relative to cells stored for one year or less at + 30°C max.)
Nominal capacity
(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)
0.45 Ah
Open circuit voltage (at + 20°C)
3.0 V
Nominal voltage
(at 0.03 A + 20°C)
2.8 V
Continuous current permitting 50% of the nominal capacity to be achieved
at + 20ºC with 2.0 V cut of f.
0.25 A
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)
Storage
(recommended)
(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)
