Proper use and handling of lithium ion cells
See before using lithium-ion cell
Supplied by
Samsung SDI Co., Ltd.
1.0. General
This document has been prepared to describe the appropriate cautions and
prohibitions, which the customer should take or employ when the customer uses
and handles the lithium ion cell to be manufactured and supplied by Samsung SDI Co.,
Ltd., in order to obtain optimal performance and safety.
2.0. Charging
2.1 Charging current
Charging current shall be less than maximum charge current specified in the product
specification.
2.2 Charging voltage
Charging shall be done by voltage less than that specified in the product specification.
2.3 Charging time
Continuous charging under specified voltage does not cause any loss of performance
characteristics. However, the charge timer is recommended to be installed from a
safety consideration, which shuts off further charging at time specified in the product
specification.
2.4 Charging temperature
The cell shall be charged within a range of specified temperatures in the specification.
2.5 Reverse charging
The cell shall be connected, confirming that its poles are correctly aligned.
Inverse charging shall be strictly prohibited. If the cell is connected improperly, it may be
damaged.
3.0. Discharging
3.1 Discharging
3.1.1 The cell shall be discharged continuously at less than maximum discharge current
specified in the product specification. In case of the higher discharge current
should be set, it shall be discussed together with SDI.
3.2 Discharging temperature
3.2.1 The cell shall be discharged within a range of temperatures specified in
the product specification.
3.2.2 Otherwise, it may cause loss of performance characteristics.
3.3 Over-discharging
3.3.1 The system should equip with a device to prevent further discharging
exceeding discharging cut-off voltage specified in the product specification.
3.3.2 Over-discharging may cause loss of performance characteristics of battery.
3.3.3 Over-discharging may occur by self-discharge if the battery is left for
a very long time without any use.
3.3.4 The charger should equip with a device to detect voltage of cell block and to
determine recharging procedures.

in the product specification.
4.1.2 Otherwise, it may cause loss of performance characteristics, leakage and/or rust.
4.2 Long-term storage
4.2.1 The cell should be used within a short period after charging because
long-term storage may cause loss of capacity by self-discharging.
4.2.2. If long-term storage is necessary, the cell should be stored at lower
voltage within a range specified in the product specification, because
storage with higher voltage may cause more loss of performance characteristics.

operating temperature and/or storage.
6.0. Design of system
6.1 Connection between the cell and the battery
6.1.1 The cell should not be soldered directly with other cells. Namely, the cell
should be welded with leads on its terminal and then be soldered with
wire or leads to solder.
6.1.2 Otherwise, it may cause damage of component, such as separator and
insulator, by heat generation.
6.2 Positioning the battery in the system
6.2.1 The battery should be positioned as possible as far from heat sources
and high temperature components.
6.2.2 Otherwise, it may cause loss of characteristics.
6.2.3 The recommended spacing between the cells is more than 1mm.
6.3 Mechanical shock protection of the battery
6.3.1 The battery should be equipped with appropriate shock absorbers in the pack
in order to minimize shock, which can damage the cells.
6.3.2 Otherwise, it may cause shape distortion, leakage, heat generation
and/or rupture and/or open circuit.
6.4 Short-circuit protection of the cell
6.4.1 The cell equips with an insulating sleeve to protect short-circuit which
may occur during transportation, battery assembly and /or system operation.
6.4.2 If the cell sleeve is damaged by some cause such as outside impact,
it may cause short-circuit with some wiring inside the battery.
6.5 Connection between the battery and charger/system
6.5.1 The battery should be designed to be connected only to the specified
charger and system.
6.5.2 A reverse connection of the battery, even in the specified system,
should be avoided by employing special battery design such as
a special terminals.
6.6 Pack design
6.6.1 The current consumption of the battery pack should be under 10uA
at sleep mode.
6.6.2 Cell voltage monitoring system.
The system (charger or pack) should be equipped with a device to monitor each

external strip terminal is welled.
7.3 Transportation
7.3.1 If the cell is necessary to be transported to such as the battery manufacturer,
careful precautions should be taken to avoid damage of cell.
8.0. Others
8.1 Disassembly
8.1.1 The cell should not be dismantled from the battery pack.
8.1.2 Internal short-circuit caused by disassembly may lead to heat generation
and/or venting.
8.1.3 When the electrolyte is coming in contact with the skin or eyes,
flush immediately with fresh water and seek medical advice.
8.2 Short-circuiting
8.2.1 Short-circuit results in very high current which leads to heat generation.
8.2.3 An appropriate circuitry should be employed to protect accidental
short-circuiting.
8.3 Incineration
8.3.1 Incinerating and disposing of the cell in fire are strictly prohibited,
because it may cause rupture and explosion.
8.4 Immersion
8.4.1 Soaking the cell in water is strictly prohibited, because it may cause
corrosion and leakage of components to be damaged to functions
8.5 Mixing use
8.5.1 Different types of cell, or same types but different cell manufacturer's shall not be
used, which may lead to cell imbalance, cell rupture or damage to system due to
the different characteristics of cell.
8.6 Battery exchange
8.6.1 Although the cell contains no environmentally hazardous component,
such as lead or cadmium, the battery shall be disposed according to
the local regulations when it is disposed.
8.6.2 The cell should be disposed with a discharged state to avoid heat generation
by an inadvertent short-circuit.
8.7 Caution
The Battery used in this device may present a risk of fire or chemical burn if
mistreated.
Do not disassemble, expose to heat above 100or incinerate it.
Replace battery with those of Samsung SDI only.
Use of another battery may cause a risk of fire or explosion.
Dispose of used battery promptly.
