Primary lithium battery LM 33550 - Saft

Primary lithium battery
LM 33550
3 V Primary lithium-manganese dioxide (Li-MnO 2
)
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
• Low self-discharge rate
(less than 2% after 1 year of
storage at + 20°C)
Key features
• Steel container
• Hermetic glass-to-metal sealing
• Built-in safety vent
• Non-corrosive electrolyte
• Restricted for transport
(Class 9)
• Made in the USA
Main applications
• Radio communication
• Measuring equipment
• Marine equipment
• ELTS, EPIRBS, etc.

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
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)
Physical characteristics (with sleeve)
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.

Storage
• The storage area should be
clean, cool, dry and ventilated
• Do not abstruct venting
mechanism
Warning
• Fire, explosion and burn hazard
• Do not recharge, short circuit,
crush, disassemble, heat above
70°C (158°F), incinerate, or
expose contents to water.
• Do not solder directly to the cell
(Use tabbed cell versions
instead.)
