Electrical characteristics

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

Nominal capacity

11 Ah

(under 100 mA at +85°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

3.6 V

(under 3 mA at +85°C)

Nominal energy

39.6 Wh

(at +85°C)

Pulse capability : Typically up to 3000 mA.

(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)

Maximum recommended continuous current

1000 mA

(at +85°C, 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/+ 85°C

(Higher temperature possible. Battery packs may imply lower level

(-76°F/+185°F)

of maximum current and may request specific thermal protection.

Consult Saft)
