They can withstand all the use, abuse, and misuse of normal industrial applications without damage. They are unaffected by vibration and can take an amazing amount of impact shock.
Does a nickel cadmium battery need ventilation?
Normal ventilation is usually adequate for the room in which a nickel cadmium battery is to be installed since slight movement of air around the emitted gases from the nickel cadmium battery do not contain fumes which are corrosive to corrosion damage. 6. How is state-of-charge determined for a nickel cadmium battery?
Does a nickel cadmium battery lose capacity?
A fully charged nickel cadmium battery in storage will gradually lose a portion of its original charge (approximately 1-3% per month). It will not, however, experience any permanent loss of capacity. Thus, after it has been recharged, it will continue to function at top performance.
