4 Intended use
These lithium batteries are intended to be used within
didactic education. These lithium batteries must be
inserted in the device STE LiIo battery holder, 739 955,
and operated in accordance with the valid associated
operating instructions. Electrical energy may only be
drawn off in conjunction with the STE LiIo battery holder,
739 955 and the Model HV battery "Cells", 739 952.
Electrical energy may only be supplied in conjunction
with the devices STE LiIo battery holder, 739 955 and
Model HV battery "Cells", 739 952, or with an approved
and suitable charger. The assembly and/or disassembly
must be done by the instructor. It must not be done by
the students!
5Fundamentals
Lithium secondary cells are chemical energy accumula-
tors that can release the stored electrical charge as elec-
trical energy through an electrochemical reaction. The
advantages of lithium batteries include their high effi-
ciency, low self-discharge, use in a wide temperature
range, high cell voltage and the absence of the memory
effect.
6 Possible hazards when handling
lithium batteries
When used properly, lithium batteries are safe. However,
if accelerated and/or uncontrolled energy release occurs,
the chemical reaction may release so much thermal
energy that a fire may result. Therefore, lithium batteries
must not be operated outside their specification.
Improper handling and incorrect use of the batteries can
result in, for example:
internal short circuits occur due to mechanical
damage
internal short circuits occur due to "revived" deeply
discharged cells (U<2.55 V)
internal short circuits occur due to thermal stress
(e.g. fire)
strong temperature increase occurs, due to
overcharging
The battery itself represents a certain source of danger
itself, if e.g.
a temperature increase occurs due to excessive
current drain or short circuit, which can lead to a
fire
an electric arc occurs due to a short circuit, which
can lead to a fire
toxic and/or flammable or explosive contents
escape, which may form an explosive mixture and
be harmful to health.
a battery bursts due to strong internal heating and
failure of the safety valve.
7 Special handling instructions
The lithium batteries described here are subjected to
greater stress during experimentation than during nor-
mal use. They therefore age more quickly and may need
to be replaced and disposed of. They are considered con-
sumables in connection with all material lists in the ex-
perimental literature! The number of charge cycles spec-
ified in the data sheets is not reached and does not rep-
resent a defect!
7.1 Charging
7.1.1 Charging current: Charging current should be less
than maximum charge current specified in the technical
data.
7.1.2 Charging voltage: Charging should be done by
voltage less than that specified in the technical data.
7.1.3 Charging time: A charge timer is recommended
to be installed from a safety consideration, which shuts
off further charging at time specified in the technical
data.
7.1.4 Charging temperature: The cell should be
charged within a range of specified temperatures in the
technical data.
7.1.5 Reverse charging: The cell should be connected,
confirming that its poles are correctly aligned. Inverse
charging is strictly prohibited. If the cell is connected
improperly, it may be damaged
7.2 Discharging
7.2.1 Discharging: The cell should be discharged at less
than maximum discharge current specified in the tech-
nical data.
7.2.2 Discharging temperature: The cell should be dis-
charged within a range of temperatures specified in the
technical data.
7.2.3 Over-discharging: The system should be
equipped with a device to prevent further discharging
exceeding discharging cut-off voltage specified in the
technical data (over-discharging). Over-discharging
may occur by self-discharge if the battery is left for a
very long time without any use. The charger should
equip with a device to detect cell voltage and to deter-
mine recharging procedures.
7.3 Storage
7.3.1 Storage conditions: The cell should be stored
within a range of temperatures specified in the tech-
nical data.
Otherwise, it may cause loss of characteristics, leakage
and/or rust.
7.3.2 Long-term storage: The cell should be used
within a short period after charging because long-term
storage may cause loss of capacity by self-discharging.
If long-term storage is necessary, the cell should be
stored at lower voltage within a range specified in the
technical data, because storage at higher voltage may
cause loss of characteristics.

7.4 Others
7.4.1 Disassembly: Internal short-circuit caused by dis-
assembly may lead to heat generation and/or venting.
When the electrolyte is coming in contact with the skin
or eyes, flush immediately with fresh water and seek
medical advice.
7.4.2 Short-circuiting: Short-circuit results in very high
current which leads to heat generation. An appropriate
circuitry should be employed to protect accidental
short-circuiting.
7.4.3 Incinerating and disposing of the cell in fire are
strictly prohibited, because it may cause rupture.
7.4.4 Immersion: Soaking the cell in water is strictly
prohibited, because it may cause melt of components
to damaged to functions.
7.4.5 Although the cell contains no environmentally
hazardous component, such as lead or cadmium. the
battery should be disposed according to the local regu-
lations when it is disposed.
7.4.6 The cell should be promptly disposed of with a
discharged state to avoid heat generation by an inad-
vertent short-circuit.
7.4.7 Caution - The Battery used in this device may
present a risk of fire or chemical burn if mistreated. Do
not disassemble, heat above 100 °C or incinerate.
