Item Test Method Benchmark
1．Appearance:
 eyeballing
 batteries shall be free from
any stains; scratches or
deformations, which may
reduce the commercial value
when visually inspected
2．Size:  caliper measurement。
 The size shall comply with the
specified size as the attached
drawing
3．Insulate
impedance
 measured with a Megger overpack
and battery electrode between the
degree of insulation。
 outer sleeve shall exceed 10
MΩ。
4．Weight  using disk-scale measurement。  approximate 29.5 g。
5．Charge
Voltage
 Following a period of discharge at
0.2CmA down to a terminal voltage
of 1.0V, standard charge, the cell or
battery shall be checked at 5 minutes
before finish charging。
 The voltage shall be less than
1.6
V。
6．Open circuit
voltage: (O.C.V.)
 Following a standard charge period,
the open circuit voltage of the cell or
battery shall be checked within 1
hour.。
 The O.C.V. shall exceed 1.25
V per cell.。
