High energy

D-size bobbin cell

(recommended for cool temperature environments)

Electrical characteristics

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

Nominal capacity

18.5 Ah

(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)

3.67 V

Nominal voltage

(at 0.7 mA + 20°C)

3.6 V

Pulse capability: Typically up to 250 mA.

(250 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)

Continuous current permitting 50% of the nominal capacity

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

80 mA

(to maintain cell heating within safe limits. Battery packs may imply lower

level of maximum current and may request specific thermal protection.

Consult Saft)

Storage

(recommended)

+ 30°C (+ 86°F) max

(for more severe conditions, consult Saft)

Operating temperature range

- 60°C/+ 70°C

(Operation above ambient T may lead to reduced capacity and

(- 76°F/+ 158°F)

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