7.9 Storage Characteristics 存储性能
Charge cells per 7.1.2. Discharge cells per 7.2.4. at 25
ºC, record the discharge capacity, and storage the
cell at the specified temperature, after finished storage , Discharge cells per 7.2.4 and record the
discharge capacity as residual capacity, and then Charge cells per 7.1.2. Discharge cells per 7.2.4.record
the discharge capacity as recoverable capacity.
25 ºC 下按照 7.1.2 方式充电,以 7.2.4 方式放电,记录放电容量,不同条件不同温度下存储电池,存储后
以 7.2.4 方式放电,记录残余容量。按照 7.1.2 方式充电,以 7.2.4 方式放电,记录恢复容量。
