50-cycle test as per above table is repeated . The discharge time of the
100th, 200th, 300th, 400th, 500th should be more than 3 hours
respectively. (Ambient temperature is 20±5)℃
5.3 Humidity
The cells shall not leak during the 14 days when it is submitted to the
condition of a temperature of 33±3 ℃ and a relative humidity of
0.25CmA for 2.33h
