3.1 Discharging
3.1.1 The cell should be discharged at less than maximum discharge current
specified in the product specification.
3.2 Discharging temperature
3.2.1 The cell should 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, of
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 cell voltage and to
determine recharging procedures.
4. Storage
4.1 Storage conditions
4.1.1 The cell should be stored within a range of temperatures specified
in the product specification.
4.1.2 Otherwise, it may cause loss of 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 at higher voltage may cause loss of characteristics.
5. Cycle life
5.1 Cycle life performance
5.1.1 The cell can be charged/discharged repeatedly up to times specified in
the produce specification with a certain level of capacity also specified
in the product specification.
5.1.2 Cycle life may be determined by conditions of charging, discharging,
operating temperature and/or storage.
6. Design of System
6.1 Connection between the cell and the battery
