Item

Condition

1

Dimensions

When measured with vernier calipers which precision is up by 0.02mm. To avoid short circuits, paste one insulation material on one end of the vernier calipers.

2

Open Voltage

the precision of the multimeter is not lower than 0.25%, intel resistance is bigger than 1MΩ

3

Instant short-circuit current

When testing with multimeters, do not surpass 0.5 seconds each time, and avoid duplicating tests, if needed once more, the time gap should be above half an hour

4

Appearance

The appearance of batteries shall be inspected by visual means.

5

Min time of discharge

Lay aside above 8 hours at a temperature of 20±2℃ and under the humidity of 60±15% conditions, with the condition that Resistance is 15kΩ, and end-point voltage is 2.0V. The new battery (Initial stage) should be tested in 60 days after production. The old battery (Delayed for 12 months) should be tested in 14 days after the storage period.

6

Over-discharge Characteristics

Take nine batteries at a temperature of 20±2℃ and under a humidity of 60±15% conditions, with the condition that Resistance is 15kΩ, and end-point voltage is 1.2V. visual test.
