Electrical characteristics

(typical values relative to cells stored for one year or less at + 30°C max.)

Nominal capacity

7.7 Ah

(at 4 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)

3.67 V

Nominal voltage

(at 0.5 mA + 20°C)

3.6 V

Nominal energy

27.72 Wh

Pulse capability: Typically up to 300 mA

(300 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

150 mA

(Higher currents possible, consult Saft)

Storage

(recommended)

+ 30°C (+ 86°F) max

(for more severe conditions, consult Saft)

Operating temperature range

- 60°C/+ 85°C

(Operation above ambient T may lead to reduced capacity and

(- 76°F/+ 185°F)

lower voltage readings at the beginning of pulses. Consult Saft)
