What is the difference between a NiCd (nickel cadmium) battery and a NiMh (nickel metal hydride) battery?

There are two main differences between the two. The NiMh battery offers a capacity that is almost twice that of the NiCd. This means longer run times without additional weight.

NiMh batteries are less prone to develop a memory effect. In addition, NiMh batteries are environmentally friendlier than the NiCd since they do not contain heavy metals. Back to Top • Can I substitute a NiMh battery for a NiCd battery?

NiCd and NiMh batteries are different from one another and cannot be substituted unless your device has been pre-configured from the factory to accept more than one chemistry type. Back to Top • Do NiCd and NiMh batteries self-discharge? Yes, these batteries will self-discharge a small amount each day.

The amount of self-discharge depends on many factors including ambient temperature. Back to Top • Must these batteries be recycled when they are no longer working? Yes.

NiMh and NiCd batteries must be recycled properly. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
