High durability Ni MH batteries, which endure 1000 discharges, are commonly packaged in bulky cylindrical cells.
Main applications are two-way radios, biomedical equipment, professional video cameras and power tools.We often get puzzled by announcements of new batteries that are said to offer very high energy densities, deliver 1000 charge/discharge cycle and are paper-thin. Another battery may be built for long life, but the size is big and bulky. While one battery type may be designed for small size and long runtime, this pack will not last and wear out prematurely.Observation: It is interesting to note that Ni Cd has the shortest charge time, delivers the highest load current and offers the lowest overall cost-per-cycle, but has the most demanding maintenance requirements.The Ni Cd prefers fast charge to slow charge and pulse charge to DC charge.
