It can be easy to overlook the importance of high-quality batteries in the function of your wireless devices. It turns out, however, a good battery is equally important for cordless tools as healthy or motor armature. Battery technology has advanced significantly since the introduction of power tools without cables; because the development of Nickel Cadmium (NiCad) battery-electric tools have evolved from NiCad to Nickel Metal Hydride (NiMH), and most recently for Lithium Ion (Li-Ion) technology.
Nickel Cadmium batteries are the first on the market for power tools without cables and even though the older technology is still very reliable. NiCad less sensitive to adverse temperatures and have a high refill cycle, which means they can be charged and recharged repeatedly for a long period.

On the downside, however, NiCad tends to suffer from the memory effect of the battery. This occurs when the battery can no longer accept a full charge because it has been repeatedly charged without first fully discharged. Battery seems to "remember" how much energy has been exhausted and only want to receive that much energy from the charger.
Cadmium is a highly toxic element that most batteries are harmful to the environment. NiCad negative effects on the environment, in fact, cause them to be taxed outside the U.S.A. As a result, many European vendors will not sell NiCad batteries.
Lithium-Ion batteries have a higher energy density than most other rechargeable batteries. A high energy density means that the Lithium-Ion has superior energy to weight ratio stores more energy for their size than most other batteries.
