7.8-1 Cycle Life
Each cycle is an interval between the charge (charge current 1.3A) with 100mA cut-off
and the discharge (discharge current 10A) with 2.5V cut-off.
Capacity after 600cycles,
Capacity ≥ 750mAh (60% of the standard capacity at 25℃)
7.8-2 Cycle Life2
Each cycle is an interval between the charge (charge current 1.3A) with 100mA cut-off
and the discharge (discharge current 15A) with 2.5V cut-off.
Capacity after 350cycles,
Capacity ≥ 750mAh (60% of the standard capacity at 25℃)
7.9 Storage Characteristics
Capacity after storage for 30days at 60℃ from the standard charge,
measured with discharge current 4A with 2.5V cut-off at 25℃.
Capacity retention(after the storage) ≥ 875mAh (70% of the capacity at 25℃)
7.10 Status of the cell as of ex-factory
The cell should be shipped in 50% charged state. In this case, OCV is from 3.65V to
3.85V.
8. Mechanical Characteristics
8.1 Drop Test
Test method: Cell(as of shipment or full charged) drop onto the oak-board
(thickness: ≥ 30mm) from 1.0m height at a random direction 6 times.
Criteria: No leakage
8.2 Vibration Test
Test method: Cell(as of shipment) is vibrated along 2 mutually
perpendicular axes with total excursion of 1.6mm and with
frequency cycling between 10Hz and 55Hz by 1Hz/min.
Criteria: No leakage

6.1 Connection between the cell and the battery
6.1.1 The cell should not be soldered directly with leads. Namely, the cell
should be welded with leads on its terminal and then be soldered with
wire or leads to soldered lead.
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.
6.3 Mechanical shock protection of the battery
6.3.1 The battery should equip with appropriate shock absorbers in order to
minimize shock.
6.3.2 Otherwise, it may cause shape distortion, leakage, heat generation
and/or rupture.
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 battery pack’s current consumption should be under 10uA at sleep mode.
6.6.2 Cell Voltage monitoring system.
- The system (Charger or Pack) should equip with a device to monitor each
Cell voltage and to stop charging if cell imbalance happen.
6.6.4 The battery pack should have warning system such as over temperature,
over voltage, over current, and so on.
