(typical values for cells stored for one year or less)
Nominal capacity
(at 0.25 A + 20°C 2.0 V cut off. The capacity restored by the cell varies
according to current drain, temperature and cut off)
3.0 V
Nominal voltage
(at 0.5 A + 20°C)
2.8 V
Maximum recommended continuous current
(to avoid over-heating. Higher currents possible, consult Saft)
2.5 A
Pulse capability : Typically up to 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)
