Test Methods

Standard

1. Dimension

Use of caliper under precision is 0.02mm or more precise，to avoid short-circuit, insulated materials should be put on the vernier caliper during test.

diameter（mm）：20.0（-0.20）

height（mm）：1.60（-0.20）

1. Open circuit voltage

Precision is 0.25% or more precise、resistance of internal circuit is bigger than 1 MΩ DDM。

3.20~3.45V

1. Instantaneous short-circuit

Using pointer multimeter for test，the time is not more than 0.5′，avoid duplicated test，the time for next test should be after half an hours.

≥300mA

1. Appearance

Visual test

Will be free from flaw, stain, deformation, uneven tone, electrolyte leakage and other defects. Installed to utensils, both terminal of battery should be under good connections.

1. Quick Discharged Volume

Standard Temperature 20±2℃，related humidity≤75%，discharge load 3kΩ，terminated voltage be 2.0V

≥80 hours

1. Vibrate test

Vibrate frequency 100-150 times per min under continuously vibration for 1 hour

Stability

7.  High temperature-resistant of weeping performance

Storage 30 days Under 45±2 conditions

leakage %≤0.0001

8.  Circuit load of weeping performance

When terminated voltage is 2.0V, continuously discharge load for 5hrs

No leakage
