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 M

Ω .

4. Weight

Using disk-scale measurement

Approximate 13.0 g.

5. Charge Voltage
