Electrical characteristics

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

Nominal capacity

17.0 Ah

(at 5 mA + 20°C 2.0V cut off. The capacity restored by the cell varies

according to current drain, temperature and cut off).

Open circuit voltage

(at + 20°C)

3.67V

Nominal voltage

(at 0.7mA + 20°C)

3.6V

Pulse capability: Typically up to 400 mA (400 mA/0.1 second pulses,

drained every 2 mn at + 20°C from undischarged cells with 10 µA base

current, yield voltage readings above 3.0V. 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)

Continuous current permitting 50% of the nominal capacity

to be achieved at + 20°C with 2.0V cut off.

250 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)
