TEST METHODS

测试方法

Dimensions外形尺寸

Using vernier caliper (accuracy≥0.02) while avoiding short-circuit.One end of the caliper should be coated with an insulating material.

用精度不低于 0.02mm 游标卡尺测量，测量时防止电池短路，卡尺的一端卡头上应贴上一层绝缘材料。

Off-load voltage

开路电压

Using multimeter (accuracy≥0.25%) internal resistance≥1MΩ.

用精度不低于 0.25%，内阻不小于 1MΩ万用表测量。

Instantaneous short-circuit current

闭路电压

Before the test, the battery should be placed under the condition of 20±2℃、RH60±15% for more than 8 hours, and then measured at the same temperature Time of short-circuit should be less than 0.5 second and avoid repeated test within half an hour.

测试前电池需在 20±2℃、RH60±15%条件下放置 8 小时以上，再在同样温度下测量。用万用表测量时，每次测量时间不超过 5 秒，避免重复测量，若需再次测量时，时间间隔应在半小时以上。

Discharge time

放电时间

Taking nine cells under the condition of 20℃±2℃、RH60%±15% place more than 8 hours, at the same temperature and humidity conditions for 30 k Ω resistance to 2.0 V, the average continuous discharge the battery discharge time should be within 60 days after the production, storage electric should be carried out within 14 days after the expiration of the storage

取9只电池在20℃±2℃、RH60%±15%条件下放置8小时以上，在相同温湿度条件下用30kΩ电阻连续放电至2.0V时的平均放电时间。电池应在生产后60天内进行，贮存电应在贮存期满后 14天内进行。
