What is the difference between a Ni-Cd and Ni-MH chemistry battery?
The main difference between the two is the fact that Ni-MH batteries (the newer of the two technologies) offer higher energy densities than Ni-Cd's. In other words, pound for pound, Ni-MH delivers approximately twice the capacity of its Ni-Cd counterpart. What this translates into is increased run-time from the battery with no additional bulk to weigh down your portable device. Ni-MH also offers another major advantage: Ni-Cd batteries tend to suffer from what is called the "memory effect". Ni-MH batteries are less prone to develop this dreaded affliction and thus require less maintenance and care. Ni-MH batteries are also more environmentally friendly than their Ni-Cd counterparts since they do not contain heavy metals (which present serious landfill problems).
