In all environmental factors, the temperature has the greatest influence on the charging and discharging performance of the battery, which is higher than 45 degrees, which has a serious effect on the performance and life of the Ni-MH Battery.
In general, high temperatures can accelerate chemical reactions, but they also speed up the aging process inside the battery. When the temperature drops, the reaction rate of the electrode decreases, the discharge current decreases, and the power output of the battery decreases. When the temperature rises to more than 45 ℃, high temperature performance degradation of rechargeable battery materials, lead to adverse reactions, battery internal resistance will increase, the cycle of the battery will shorten the service life.
We are China professional Ni-Mh, Ni-MH Battery Pack Manufacturer and Supplier.
