This fairly recent entry into the rechargeable field offers up to
40% additional power capacity than the traditional NiCd’s of equal size.

Also, from an environmental aspect, these batteries are far more acceptable
than NiCd’s, as they will breakdown with little or no harmful effect on the environment.

Nickel Metal Hydride batteries are commonly found in
cell phone applications, laptop computers and camcorders.

They have about 20% more power than Ni-cad batteries and weigh about 20% less.
