What is high temperature and high humidity detection?

The detection of high temperature and humidity of Ni-MH battery is as follows: After the battery is overcharged, store it under the conditions of constant temperature and humidity for several days, and observe whether there is any leakage during the storage process. The detection of high temperature and humidity of lithium-ion battery is as follows: (national standard) charge the battery to 4.2V with 1C constant current and constant voltage, cut-off current 10mA, and then put it into (40±2)℃, relative humidity 90%-95% constant temperature and constant temperature After leaving it in the wet box for 48h, take out the battery and leave it at (20±5)℃ for 2h. Observe that the appearance of the battery should be normal. Then discharge to 2.75V at a constant current of 1C, and then at (20±5)℃. Then, carry out 1C charge and 1C discharge cycles until the discharge capacity is not less than 85% of the initial capacity, but the number of cycles is not more than 3 times.
