Primary lithium battery

LM 33550

Benefits

during most of the lifetime of the

application

dormant periods

current and low temperature

systems

(less than 2% after 1 year of

storage at + 20°C)

Key features

(Class 9)

Main applications

Electrical characteristics

(Typical values relative to cells stored for one year or less

at + 30°C max.)

Nominal capacity

13 Ah

(at 250 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)

3.2 V

Nominal voltage (under 1 mA at + 20°C)

3.0 V

Pulse capability : Typically up to 8 A

(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

4 A

(To maintain cell heating within safe limits)

Storage (recommended)

+ 30°C (+ 86°F) max

(for more severe conditions, consult Saft)

Operating temperature range

- 40°C /+ 70°C

(Operation below ambient T may lead to reduced capacity and

lower voltage readings)

Diameter (max)

34.2 mm (1.35 in.)

Height (max, without tabs)

61.4 mm (2.42 in.)

Typical weight

120 g (4.23 oz)

Li metal content

approx. 3.7 g

Standard cell comes with vent washer at the bottom and two radial

0.15 mm thick nickel tabs. Other configurations available on request.

3 V Primary lithium-manganese dioxide (Li-MnO

High power

D-size spiral cell

Cell size reference

R20 - D

For applications requesting

excellent voltage response and

operating life in - 40°C/+ 70°C
