Electrical characteristics
(typical values relative to cells stored for one year or less at + 30 °C max.)
Nominal capacity
(at 1 mA + 20 °C 2.0 V cut-off. The capacity restored by the cell varies
according to current drain, temperature and cut-off)
Open circuit voltage (at + 20°C)
Nominal voltage
(at 0.1 mA + 20°C)
1.20 Ah
3.67 V
3.6 V
Nominal energy
4.32 Wh
Pulse capability: Typically up to 100 mA
(100 mA/0.1 second pulses, drained every 2 mn at + 20 °C from
undischarged cells with 10 µA base current, yield voltage readings above
3.0 V. The 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)
Maximum recommended continuous current
(Higher currents are possible, consult Saft)
Storage 35 mA
(recommended)
(for more severe conditions, consult Saft)
Operating temperature range
(Operation above ambient T may lead to reduced capacity and lower voltage readings at the beginning of pulses. Consult Saft)
