Primary lithium battery
LM 33550
3 V Primary lithium-manganese dioxide (Li-MnO2)
High power
D-size spiral cell
For applications requesting
excellent voltage response and
operating life in - 40°C/+ 70°C
environments
Benefits
• High voltage response, stable
during most of the lifetime of the
application
• High drain/pulse capabilty
• Minimum voltage delay after long
dormant periods
• Competitive capacity at high
current and low temperature
• Easy integration into compact
systems
Cell size reference
R20 - D
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
3.0 V
Nominal voltage (under 1 mA at + 20°C)
Pulse capability : Typically up to 8 A
• Low self-discharge rate
(less than 2% after 1 year of
storage at + 20°C)
(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
(To maintain cell heating within safe limits)
Storage (recommended)
4 A
