What should be paid attention to when using Ni-MH battery?
(1) Use process avoid overcharge. In the cycle life, the use of the process should not be charged, this is because the overcharge is easy to make positive and negative expansion, resulting in the loss of active materials and diaphragm damage, conductive network damage and battery ohm polarization become large and so on.
(2)Prevent the electrolyte from deteriorating. In the cycle Life of Ni-mh battery, hydrogen hydride should be suppressed.
(3)Ni-MH battery storage. The preservation of Ni-MH batteries should be sufficient electricity, if the battery does not store electricity in the case of long-term preservation of the battery, will make the battery cathode hydrogen storage alloy function weakened, and lead to short battery life.
(4) charge after the battery is exhausted. Ni-mh batteries and Ni-CD batteries are the same, there is a "memory effect", that is, if the discharge in the battery is still residual electricity in the state of repeated charging use, the battery will soon not be used.
