Note: If charge temperature and discharge temperature is not the same,
the interval for temperature change is 3 hours.
Percentage index of the discharge at 25℃ at 10A (=1,950mAh) is 100%.
7.7 Temperature dependence of charge capacity
Capacity comparison at each temperature, measured with discharge constant current
10A and 2.5V cut-off after the standard charge is as follows.

Note: If charge temperature and discharge temperature is not the same,
the interval for temperature change is 3 hours.
Percentage index of the discharge at 25℃ at 10A (=1,950mAh) is 100%.
7.8 Charge rate capabilities
Discharge capacity is measured with constant current 10A and 2.5V cut-off
after the cell is charged with 4.2V as follows.

7.10 Cycle life
With standard charge and maximum continuous discharge.
Capacity after 250cycles,
Capacity ≥ 1,200mAh (60% of the nominal capacity at 25℃)
7.11 Storage characteristics
Standard rated discharge capacity after storage for 1 month at 60℃ from the standard
charged state is ≥ 90% of the initial 10A discharge capacity at 25℃
7.12 Status of the cell as of ex-factory
The cell should be shipped in 50 ± 5% charged state. In this case, OCV is from 3.600V
to 3.690V.

voltage of cell block to avoid cell imbalance which can cause damage to the cells.
6.6.4 The battery pack or system should have warning system such as over
temperature, over voltage, over current, and so on.
7.0. 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-distorsion and/or
electrolyte-smell is detected.
7.2 Terminals handling
7.2.1 Excessive force on the negative terminal should be avoided when
external strip terminal is welled.
7.3 Transportation
7.3.1 If the cell is necessary to be transported to such as the battery manufacturer,
careful precautions should be taken to avoid damage of cell.
8.0. 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.
8.1.3 When the electrolyte is coming in contact with the skin or eyes,
flush immediately with fresh water and seek medical advice.
8.2 Short-circuiting
8.2.1 Short-circuit results in very high current which leads to heat generation.
8.2.3 An appropriate circuitry should be employed to protect accidental
short-circuiting.
8.3 Incineration
8.3.1 Incinerating and disposing of the cell in fire are strictly prohibited,
because it may cause rupture and explosion.
8.4 Immersion
8.4.1 Soaking the cell in water is strictly prohibited, because it may cause
corrosion and leakage of components to be damaged to functions
8.5 Mixing use
8.5.1 Different types of cell, or same types but different cell manufacturer's shall not be
used, which may lead to cell imbalance, cell rupture or damage to system due to
the different characteristics of cell.
8.6 Battery exchange
8.6.1 Although the cell contains no environmentally hazardous component,
such as lead or cadmium, the battery shall be disposed according to
the local regulations when it is disposed.
8.6.2 The cell should be disposed with a discharged state to avoid heat generation
by an inadvertent short-circuit.
8.7 Caution
The Battery used in this device may present a risk of fire or chemical burn if
mistreated.
Do not disassemble, expose to heat above 100℃ or incinerate it.
Replace battery with those of Samsung SDI only.
Use of another battery may cause a risk of fire or explosion.
Dispose of used battery promptly.
