Proper use and handling of lithium ion cells
See before using lithium-ion cell
Supplied by
Samsung SDI Co., Ltd.
1. 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 optimum performance and safety.
2. 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 appropriate voltage does not cause any loss of
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 product specification.
2.5 Reverse charging
The cell shall be connected, confirming that its poles are correctly aligned.
Inverse charging should be strictly prohibited. If the cell is connected
improperly, it may be damaged.
3. Discharging
3.1 Discharging
3.1.1 The cell shall be discharged at less than maximum discharge current
specified in the product specification.
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 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.(over-discharging)
3.3.2 Over-discharging may cause loss of performance, characteristics and
battery function.
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.
