7.8 Cycle Life
Each cycle is an interval between the charge (charge current 1475mA) with 3.0h or
0.05C cut-off and the discharge (discharge current 1475mA) with 2.75V cut-off.
Capacity after 299cycles and plus 1 day, measured under the same condition
In 7.2
Capacity ≥ 1995mAh(70% of the capacity at 25℃)
Storage cell over a period of time (especially over 1 month) is expected to show
normal low temperature cycle performance ( below 10’C), after it is pre-cycled(3*)
5 times at room temperature.
(3*) Pre-cycling: Each cycle is an interval between the charges (charge current
2360mA) with 3.0h or 0.05C cut-off and the discharge (discharge current 1475mA)
with 3.0V cut-off.
7.9 Storage Characteristics
Capacity after storage for 30days at 25℃ from the standard charge,
measured with discharge current 590mA with 2.75V cut-off at 25℃.
Capacity retention(after the storage) ≥ 2280mAh (80% 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 4feet 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

1.1
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
special terminals.
7. Battery Pack Assembly
7.1 Prohibition of usage of damaged cell
7.1.1 The cell should be inspected visually before battery assembly.
7.1.2 The cell should not be used if sleeve-damage, can-distortion and/or
electrolyte-smell is detected.
7.2 Terminals handling
7.2.1 Excessive force on the negative terminal should be avoided when
external lead is welled.
7.3 Transportation
7.3.1 If the cell is necessary to transported to order place, such as the
battery manufacturer, careful precautions should be taken to avoid
damage of cell.
8. 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.
