How do NiCad (Nickel Cadmium) and Nickel Hydride batteries compare?

Nickel Hydride batteries have a higher energy density than Nickel Cadmium batteries, so batteries are smaller for a given capacity. This is useful if you have a small model which it is difficult to fit the required number of batteries in to. They also do not contain cadmium, and do not therefore require special disposal.

However, they are more expensive than NiCad batteries and are slightly less forgiving of mistreatment. If you have the space, NiCad are a cheaper and better choice for model railway applications. 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.
