Temperature Dependence of discharge capacity(放电温度特性)
Cells shall be charged per 3.3.1 and discharged @0.2 C5A to 2.0 volts.Except to be discharged at temperaures
per Table 3. Cells shall be stored for 3 hours at the test temperature prior to discharging and then shall be discharged
at the test temperture.The capacity of a cell at each temperture shall be compared to the capacity achieved at 23℃
and the percentage shall be calculated.Each cell shall meet or exceed the requirements of Table 3.
电池按 3.3.1 规定充电。按表 3 的温度中放电,电池必须先在该试验温度中放置 3 个小时。在每一个温
度中的放电容量应不小于表 3 的要求。
