How to maintain NiMH battery and NiMH battery’s development trend


(1) Avoid overcharging during use. During the cycle life, overcharge should be avoided in the use process, because overcharge is easy to expand the positive and negative electrodes, resulting in active material falling off and diaphragm damage, conductive network damage and battery ohmic polarization.

(2) Prevent electrolyte deterioration. During the cycle life of Ni MH battery, hydrogen evolution of battery shall be restrained.

(3) Storage of Ni MH batteries. After the Ni MH battery is fully charged, if the battery is stored for a long time without electric energy stored in the battery, the function of the negative hydrogen storage alloy of the battery will be weakened and the battery life will be shortened.
