Spec. No. INR18650-20Q Version No. 1.0
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 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.
5.0. Cycle life
5.1 Cycle life performance
5.1.1 The cell can be charged/discharged repeatedly up to times specified in
the product specification with a certain level of capacity specified in the
5.1.2 Cycle life may be determined by conditions of charging, discharging,
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
