Condition
The test is carried out with new batteries (within a month after
delivery). ambient conditions:
Condition for
standard operation Temperature: 20±5℃
Humidity：65±20%
Tolerances ±5‰ for voltage and current
charging at a constant current of 0.1C(4mA) for 16h.
(1)Normal Charge Prior to charging, the cell shall have been discharged at a
constant current of 0.2C(8mA), down to a final voltage of
1.0V/cell.
(2)Open Circuit
Voltage (OCV)
After 1 hour normal charge
The cell shall be charged. After charging, the cell shall be
stored for 1h,then the cell shall have been discharged at a
constant current of 0.2C(8mA), down to a final voltage of
1.0V/cell. five cycles are permitted for this test.

DATA SHEET
Prior to this test,the cell shall be discharged .The cell shall then
be charged at a constant current of 0.1C(4mA)for 48h. After
this charging operation,the cell shall be stored 1h,The cell shall
then be discharged at a constant current of 0.2C(8mA)to a final
voltage of 1.0V/cell.
The charged cell is stored for 28 days .And the discharge time
is measured at normal discharge.

(6)Life expectancy
(IEC cycle)
50
Cycles 1 to 50 shall be repeated until the discharge duration on
any 50th cycle becomes less than 3h. At this stage, a repeat
capacity measurement as specified for cycle 50 shall be carried
out.The endurance test is considered complete when two such
successive capacity cycles give a discharge duration of less than
3h. [IEC61951-2:(2003)7.4.1.1]
4.PRECAUTION
4.1 Never short-circuit or reverse polarity in application.
4.2 Avoid throwing cells into a fire or attempting to disassemble them.
4.3 This is not safety: use the cell without the specified working temperature range, charge and
discharge with more than our specified current.
4.4 Do not mix batteries with metal objects during storage or transportation to avoid accidental short-
circuit.
