hour。
8．Internal
impedance
 Following a standard charge period,
the internal impedance of the cell or
battery shall be checked at 1000Hz
within 1 hour。
 The internal impedance shall
not be more than 32 mΩ per
cell.。
9．capacity
 Following a standard charge period,
the cell shall be stored for a period
of 1 hour. The capacity shall be
equal or more than minimum
capacity when discharged at 0.2C
mA down to a terminal voltage of
1.0V；
 The capacity returned might not
initially attain the specified value
following the first charge –discharge
cycle. In this event, the test may be
repeated a further two or three times
to attain the minimum capacity。
 The capcity is greater than or
equal to the minimum
capacity。
10．High Drain
Discharge
 To discharge by 0.5C to 1.0V within
1 hour after standard charge。
 The Capacity is higher than or
equal to 114 min。
11．Over-charge
 Following a period of discharge at
0.2C mA down to a terminal
voltage of 1.0V，standard charge
and then charge for 48hrs at 0.1C
mA. The capacity of the cell or
battery shall not be less than the
rated capacity when discharged at
0.2C mA。
 It shall not be externally
deformed and no leakage of
electrolyte in liquid form shall
be observed.。
12．Over-
discharge
★★★★★
 Following a period of discharge at
0.2C
mA down to a terminal
voltage of 1.0V, combine the cells
with a 0.86 Ωper cell load. After
stored for a period of 24 hours,
standard charged and then discharge
at 0.2C mA。
 the cell or battery shall not be
externally deformed and no
leakage of electrolyte in liquid
form shall be observed, and
the subsequent capacity shall
not be less than 98% of rated
capacity。★
 Following a period of discharge at
0.2C mA down to a terminal
voltage of 1.0V, standard charge and
then the cell or battery shall be
stored for 180 days below 20℃。
 The subsequent capacity shall
not be less than 85%
of
rated capacity when
discharged at 0.2C mA。.
★
13．Self
discharge
★★★★★
 Following a period of discharge at
0.2C mA down to a terminal
voltage of 1.0V, standard charge and
then the cell or battery shall be
stored for 360 days below 20℃。
 The subsequent capacity shall
not be less than 80% of
rated capacity when
discharged at 0.2C mA。.
